Version 1.30 MENU SELECTION: Esc Screen 1 of 1 Press the escape key (labeled "Esc") to exit the current menu (regardless of the current position of the inverse cursor box) and return to the initial system selection menu: Displays Archive Configure Protocol analysis Quit Alternatively, place the inverse cursor box over the Esc selection (as it is now) using the left/right arrow keys and press the Enter key. ARCHIVE SETUP Screen 1 of 3 FUNCTION: Set archive Drive, Path, Filename, and file view Extension Filter. Set archive length (in Kilobytes) and archive storage chunk size (in Bytes). Enable or disable the background archiving process and auto halt mechanism. FIELDS: Read the bottom letter box for field input help. Drive Letter: Standard DOS drive letter A through Z. Upper and lower case characters are acceptable. Filename: Standard unique DOS filename, including extension, for the archive file. Only valid filename characters are allowed. No path characters are acceptable - include them in the Path field. Path: Full DOS path specification. For example, a single "\" would indicate a file in the root directory. Paths beginning without a backslash are relative to the current directory. Lack of any path specification is also relative to the current directory. Extension Filter: Previously created archive files can be viewed using the F3 function key. Enter the file extension of interest with or without wildcards "?" and "*". No entry (a blank field) is equivalent to "*". Length: Set the size of the archive file in Kilobytes. The range is from 32 to 8192 Kilobytes. The actual number of data bytes that the archive will hold is one quarter of this number (records are four bytes long containing one signal byte, one data byte, and two time stamp bytes) if time stamping is enabled, or one half of this number if time stamping is disabled. ARCHIVE SETUP Screen 2 of 3 Chunk Size: Set the archive minimum trip value in bytes. The range is 2048 to 32768 bytes. The actual number of data bytes required to trip the archive is one quarter or one half of this value depending upon whether or not time stamping is enabled (Chunk sizes are in bytes, not records). Archiving: Enable or disable background archiving upon exit from the setup screen. Current archive data (if any) will be undisturbed. Enable archiving outside of the Archive Setup screen by pressing Alt-E to append to the current archive and Alt-F to begin a fresh archive. Auto Halt: Enable or disable the mechanism that halts background archiving whenever the current archive file becomes filled with data. This mode stays in force until manually deactivated, or until the capture mode is initiated. ACTIVATION: Esc: Normal exit of the setup screen effects change to the archive enable/disable, the auto halt mechanism and the Chunk size. F1: Press the F1 function key to change the file specification using the Drive, Filename and Path only. The file length will not be altered. Use F1 when changing to a previously captured file to prevent loss of data due to an inadvertent size alteration. ARCHIVE SETUP Screen 3 of 3 F2: Press the F2 function key to size a file specified by the Drive Letter, Filename and Length fields. Selecting a previously created archive file with a size other than the file's original size will destroy any data contained in the file. (Use F1 to re-select old files). Use F2 to create new files - if there is no such filespec, the program will allow creation of the filespec with the currently specified length. F3: View the archive files in the directory specified by Drive Letter and Path. Use the Extension Filter to reduce the number of displayed files by filtering with or without the "?" and "*" wildcards. Press Esc to exit the file viewer without changing the Filename. Press Enter to update the Filename from the highlighted selection in the file viewer. Use the up/down arrow keys to move the inverse cursor box and scroll long directory listings. Home and End move the inverse cursor box also. TECHNICAL INFORMATION: Manipulate the Length and Chunk Size to optimize the archiving process to your hardware platform and operating conditions. Follow these simple rules: Increase the Chunk size for slow disks. Increase the Chunk size and archive size for high data rates. Keep the Chunk size less than half of the archive Length at all times. Also increase the number of swing buffers (see the Capture Setup Screen, Alt-C, for further information) for high average and/or burst data rates. The importance of these factors is inversely proportional to the platform speed. PORT SETUP Screen 1 of 2 FUNCTION: Set baud rate, parity, stop and data bits, and output signals for each port. FIELDS: All fields are related to the selected port. Port: Establish all other values relative to this field. Valid ports are COM1 and COM2. Baud Rate: Select from a list of valid baud rates by pressing the space bar or up/down arrow keys. Valid baud rates are User and 50 to 115,200. User Baud: Select a non-standard baud rate. Input values will automatic- ally be adjusted to actual hardware supported rates (integer timer preset values for the baud rate generator). Valid baud rates: 1 to 38,400. Parity: Select from none, odd, even, mark, and space parity. Stop Bits: Select from one or two stop bits. Data Bits: Select from five to eight data bits. RTS: Set the value of the RTS output line. Asserted is a marking (low voltage) state. DTR: Set the value of the DTR output line. Asserted is a marking state. OUT1: Determine the output of the first of two application dependent output lines. This line is normally unused. OUT2: Control the availability of input interrupts to the 8250 uart on IBM compatible communication adapters. This line must be asserted to allow character reception interrupts. PORT SETUP Screen 2 of 2 FIELDS: continued ... Line Break: Asserts a continuous spacing state on the line when the selection reads asserted. Unasserted is the default, and normal, operating selection. When a line break is asserted on a given port, transmission is inhibited. CAPTURE MODE SETUP Screen 1 of 2 FUNCTION: Set the capture mode trigger pattern and related constants. FIELDS: All field contents become active upon exiting the setup screen. Port: Select port specific field values for all other fields in the screen. Triggering can only occur on one port at a time, but separate port specific values are maintained at all times. Capturing: Control the enable/disable status of the capture mode upon exit of the Capture Mode Setup screen. Enable the capture mode outside of this screen by pressing Alt-M. Swing Buffers: Set the number of 65,536 byte ram buffers allocated for interrupt driven character record reception. Increase this value when operating with the largest Chunk Size and/or high average or burst data rates. Trigger Pattern: Enter up to thirty-two bytes of binary data into the trigger pattern. Incoming characters are sequentially scanned against this pattern until a match is detected. Chunk Size: For convenience, the Chunk Size field is repeated in this setup screen. Chunk Size will influence the selection of the capture count. This field is active and can be altered as in the archive setup screen. Changes made here will be reflected throughout the program. Chunk Size is expressed in bytes, not records. CAPTURE MODE SETUP Screen 2 of 2 FIELDS: continued ... Occurrences: Allow multiple occurrences of the preset trigger to pass without initiating capture cancellation. On the final occurrence of the trigger string, the capture mechanism will count down the preset Capture Count until it reaches zero, cancelling archiving. Capture Count: Determine the number of archive chunks that will be saved before automatic cancellation of archiving after detecting the final occurrence of the Trigger Pattern match. RELATED INFORMATION: Enable capture trigger matching outside of this screen by pressing Alt-M (for match). Within the screen, use the Capturing field. The true length of the Trigger Pattern is displayed on the screen immediately following its field to verify the intended pattern length. TECHNICAL INFORMATION: The main status and capture displays indicate the state of the capture mechanism. Disable capturing manually by simply turning off the archiving mechanism via the archive menu Disable selection or the Alt-D hot key. All data captured up to the moment will be preserved, so there is no penalty for early manual termination due to incorrect capture count or trigger pattern. CHARACTER TRANSLATION EDITOR Screen 1 of 3 FUNCTION: Set any character's attributes and/or translation string for display. Change the current character set, mode or number base. NOTE: All fields are dependent upon Port and Number Base. FIELDS: All numeric values are displayed in the currently selected base. Port: Set the context of the character translation information (except Number Base). Translation String: Updated whenever the character value is edited, this field (together with the F1 function) alters translation strings to any set of one to six alphanumeric characters (excepting nulls). Number Base: Set the system wide number conversion and character display base. Certain values are excluded from the number base effect, such as interrupt vectors, which are always entered and displayed in hexa- decimal. The History GoTo field is always entered in decimal to conform to Record and Character numbering. Changing the number base will alter the dependent field contents to allow immediate reference. Character: Edit this field to update the Translation String and Attributes fields to display the current translation of the chosen Character. CHARACTER TRANSLATION EDITOR Screen 2 of 3 FIELDS: continued ... Attributes: Indicating the current attributes of the Translation String, edit the field (in conjunction with the F1 function) to alter the attributes of a Character representation. Edit with digits in the currently selected base. Mode: Select from one of two translation modes: Ascii - uses the normal ascii character set below 128 decimal and numeric representations above 127 decimal. Numeric - uses strictly numeric representations regardless of value. Translation strings in both modes are user alterable; it is useful, however, to retain the character vs. numeric distinction. Low: Set the global character range low value. Global attribute change activations will include this character. High: Set the global character range high value. Global attribute change activations will include this character. CHARACTER TRANSLATION EDITOR Screen 3 of 3 ACTIVATION: F1: Press F1 to save the translation and attributes for the selected Character value and the selected Port for the current Number Base and Mode. Character sets are distinct for each Port, Mode and Number Base, comprising twelve unique translation sets. Save all changes individu- ally - they are not memorized automatically. F2: Press F2 to globally acquire the current Attributes. Globally, that is, within the current Port, Mode and Number Base for all Character values encompassed by the inclusive range of Low through High. The default translation set uses normal attributes for com1 and high- intensity attributes for com2. Custom attribute selection and translation is encouraged. TECHNICAL INFORMATION: There are two independent fields: Port and Number Base. All other fields depend upon Port and Number Base. There are six distinct character sets for each Port (an Ascii and Numeric set for each of the three number bases: Octal, Decimal and Hexadecimal). These character sets are fully independent of each other, so it is possible to have different color schemes and/or character translations in each. INTERRUPT VECTOR SETUP Screen 1 of 2 FUNCTION: Set base addresses and interrupt vectors for each port. Take great care when altering these values. Incorrect address selection can easily crash a system by I/O activity in pre-assigned locations. In- correct vector selection can cause replacement of a vital system inter- rupt service routine. Be sure to disable any interrupt used by other devices - such as mice. FIELDS: All field contents become active upon exiting the setup screen. Port: Select the port context for all other fields. Base Address: Com1 and Com2 have default base addresses of 3F8 and 2F8, respectively. Some manufacturers make ports with alterable addressing. Follow the manufacturer's guidelines for selecting a base address and set this field (in Hex) to conform to the chosen address. IRQ Number: Identifies the interrupt level for the port. Com1 and Com2 normally default to levels 4 and 3, respectively. Once again, when installing a port, follow the manufacturer's instructions and set the interrupt vector level to conform to the hardware. Installed: Activate and deactivate port interrupts. Often there is another device using a port interrupt (mice, for example). The use of an interrupt can be prevented by selecting No for this field. INTERRUPT VECTOR SETUP Screen 2 of 2 FIELDS: continued ... Cable Type: Set the type of cable in use. DataScope operates with three types of cables: Modulink (tm), BreakOut (tm) and Serialtest (tm). When the BreakOut (tm) selection is active, COM1 and COM2 are defined as DCE and DTE, respectively, regardless of the Device Assignments field choice. Modulink (tm) and Serialtest (tm) allow port and device assignment. Event Mask: Select the type of events that are of interest. You can opt- imize system operation by eliminating signal or data interrupts if they are of no interest or consequence. If signals are not enabled, some signal changes will not be detected, depending upon device assignments. Time Stamping: Eliminate time stamping (reducing interrupt overhead by approximately thirty percent) to accommodate ultra-high throughput applic- actions or to compensate for poor platform performance. For most situat- ions, however, time stamping is desirable and quite useful. Device Assignments: Select the desired device assignments in this field or set the auto selection mode to allow the smart cables to dictate assignments. A word of caution, however. Breakout (tm) cables do not allow sensing and must be assigned as follows: COM1: DCE, COM2: DTE. Modulink (tm) and Serialtest (tm) cables allow smart sensing. Sensing can be overridden by this field to change the data labelling. This action will invalidate signal information from the cables, but cause no damage. INTERRUPT VECTOR SETUP ***Unused*** Screen 3 of 3 TECHNICAL INFORMATION: Device assignment can cause an enormous amount of confusion, particularly concerning the origination and meaning of RS-232 signals. Quite often, monitoring DTE/DTE communications, the nomenclature becomes somewhat inadequate. OPTIONS SETUP Screen 1 of 1 FUNCTION: Select various unrelated system options to adjust the program's performance for different levels of compatibility and platform power. FIELDS: All field contents become active upon exiting the setup screen. Video Mode: Select from three video modes: Native, BIOS and Hybrid. BIOS selection restricts screen display functions to those supported by BIOS. Hybrid gains a performance increase by directly writing to the video memory, and is for use on any 100% IBM compatible machine. Native eliminates all BIOS functions (except keyboard input) to further increase efficiency (also for use on 100% IBM compatible machines, only). Slow Live Displays: Good line efficiency at high continuous data rates hopelessly outdates live display information. Select the skip function to allow real-time displays to skip ahead in the buffered data, providing more current information. Skips will never prevent the display of the final screenful of data even if the source or sources suddenly quit. Control-C Response: Enable the functionality of Control-C as a quick program termination. When enabled and Control-C is depressed, the program immediately exits to DOS, regardless of the current state or function. Screen Saver Delay: Set the screen saver delay time in minutes (from one to nine). A value of zero disables the screen saver mechanism. Hot keys, Control-C and Esc are active while the screen is blanked (they recover the screen and perform their normal actions in one keystroke). INTERACTIVE MODE SETUP Screen 1 of 2 FUNCTION: Determine the interactive mode filespec (Drive, Path and Filename) for transmission by the Insert key. FIELDS: All field contents become active upon exiting the setup screen. Filename: Enter a standard unique DOS filename, including extension. No wildcard or path divider characters are allowed. Drive Letter: Standard DOS drive letter A through Z. Upper and lower case characters are acceptable. Path: Full DOS path specification. For example, a single "\" would indicate a file in the root directory. Paths beginning without a backslash are relative to the current directory. Lack of any path specification is also relative to the current directory. Extension Filter: The list of transmission files can be viewed using the F3 function key. Enter the file extension of interest with or without wildcards "?" and "*". No entry (a blank field) is equivalent to "*". INTERACTIVE MODE SETUP Screen 2 of 2 ACTIVATION: F3: Press F3 to view the selection of configuration kernels in the directory specified by the Drive Letter and Path. Use the Extension Filter to reduce the number of displayed files by filtering with or without the "?" and "*" wildcards. Press Esc to exit the file viewer without changing the Filename. Press Enter to update the Filename from the highlighted selection in the file viewer. Use the up/down arrow keys to move the inverse cursor box and scroll long directory listings. Home and End move the inverse cursor box also. RELATED INFORMATION: File transmission is simple and useful. The primary concern is that only the intended characters get transmitted. The entire contents of the file will be transmitted, so carefully exclude unwanted line and file control characters when editing the transmission file. KERNEL (CONFIGURATION) SETUP Screen 1 of 3 FUNCTION: Specify a pre-existing configuration set (kernel) or build a new set using the current configuration. FIELDS: Read the bottom letter box for field input help. Filename: Enter a standard unique DOS filename, including extension. No wildcard or path divider characters are allowed. Drive Letter: Standard DOS drive letter A through Z. Upper and lower case characters are acceptable. Path: Full DOS path specification. For example, a single "\" would indicate a file in the root directory. Paths beginning without a backslash are relative to the current directory. Lack of any path specification is also relative to the current directory. Extension Filter: The list of configuration files can be viewed using the F3 function key. Enter the file extension of interest with or without wildcards "?" and "*". No entry (a blank field) is equivalent to "*". KERNEL (CONFIGURATION) SETUP Screen 2 of 3 ACTIVATION: F1: Press F1 to select the kernel specified by Drive Letter, Filename and Path. If the file exists, it will become the current configuration. If the file does not exist, you will be asked if you wish to create such a file. If you answer yes, the new file will contain all of the current configuration information. F3: Press F3 to view configuration kernels in the directory specified by the Drive Letter and Path, filtered by the Extension Filter. Use the Extension Filter to reduce the number of displayed files by filtering with or without the "?" and "*" wildcards. Press Esc to exit the file viewer without changing the Filename. Press Enter to update the Filename from the highlighted selection in the file viewer. Use the up/down arrow keys to move the inverse cursor box and scroll long directory listings. Home and End move the inverse cursor box also. KERNEL (CONFIGURATION) SETUP Screen 3 of 3 RELATED INFORMATION: DataScope remembers the last configuration used, and will attempt to power- up with this configuration unless you specify a kernel switch with /c or /C. Full path specification is allowed but not required. For example, pals /c original.cfg will override the last kernel and utilize original.cfg from the same directory containing pals.exe. /C \pals\other.cfg will override the last kernel and utilize other.cfg from the pals directory regardless of the current directory or the directory containing pals.exe. The hierarchy of kernel specification is thus: Switches; Last; pals.cfg in the specified environment variable directory, if any; pals.cfg in the current directory. 30 33 36 39 42 45 QUICK REFERENCE GUIDE Screen 1 of 2 Function Key Operations: F1 - Setup Screen function activation (unique to each screen). F2 - Setup Screen function activation (unique to each screen). F3 - File viewer (Archive, Kernel and Interactive setup screens). F4 - Undefined. F5 - Undefined. F6 - Undefined. F7 - Undefined. F8 - Undefined. F9 - Toggles current communications port selection on status screen. F10 - Displays Quick Reference Guide when main status screen is visible. Hot Key Summary (upper and lower case characters are allowed): Alt-O - Program options. Alt-P - Port setup. Alt-A - Archive file options. Alt-C - Capture mode setup. Alt-T - Character translations. Alt-V - Interrupt Vector setup. Alt-I - Interactive mode setup. Alt-K - Kernel (configuration) setup. Alt-F - Enable fresh archiving. Alt-D - Disable all archiving/capturing. Alt-E - Enable archive appending. Alt-M - Match (capture) enable. Alt-S - DOS shell. QUICK REFERENCE GUIDE Screen 2 of 2 Press the first letter of a menu selection (or use the left and right arrow keys to position the inverse cursor box over the desired function and press Enter) to activate. Press the Esc key (not the letter "E") for single key activation of the Esc option. PATH ENVIRONMENT VARIABLE "PALS": Configuration kernels and help files are not required to reside in the same directory as the executable file. The environment variable PALS will override the default current directory search path unless the files do not exist in the PALS specified directory. For more information on environment variables and their impact on path searches consult the user manual. CONFIGURATION MEMORY: DataScope remembers the last configuration used, and will attempt to power-up with this configuration unless you specify a kernel switch with /c or /C. Full path specification is allowed but not required. For example, pals /c original.cfg will override the last kernel and utilize original.cfg from the current directory. /C \pals\other.cfg will override the last kernel and utilize other.cfg from the pals directory regardless of the current directory or the directory containing pals.exe. The hierarchy of kernel specification is thus: Switches; Last; Environment variable directory pals.cfg; Current directory pals.cfg. MENU SELECTION: Displays Screen 1 of 1 Active this menu selection to enter the display sub-menu allowing selection of seven different displays: History: Display captured archive file data with two active cursors, optional time stamp information, and character/string search functions. Capture: Display swing buffer and archive file usage in real-time along with archive and capture mode status. Single: Invoke a live character display of the current port using data from the ram swing buffers. Dual: Invoke live character data displays for both ports in separate windows. Mixed: Display live character data from both ports (intermixed on the same lines) in order of reception into the swing buffers. Alternating: Display live character data from both ports (on separate lines) in order of reception. Interactive: Transmit characters from the keyboard and files while displaying character input for the current port on the normal (alternating) lines. (Transmission characters, including keystrokes are displayed as though originating from the line partner. If both interrupts are enabled, non-interactive port data will still be displayed (interspersed with trans- mission characters) in order of appearance. MENU SELECTION: Archive Screen 1 of 1 Activate this menu selection to enter the archive sub-menu allowing archive setup and control. All functions in this sub-menu can be directly accessed using Hot keys. PathSpec: Enter the Archive setup screen. Hot key = Alt-A.

Options: Enter the Options Setup screen where user configurable display, and Control-C options are set. Hot key = Alt-O. MENU SELECTION: Protocol Analysis Screen 1 of 1 Activate this menu selection to enter the protocol analysis sub-menu. *** This feature is not installed *** 54 55 56 57 58 MENU SELECTION: Quit Screen 1 of 1 Activate this menu selection to prompt for verification of intent to exit DataScope to DOS. A negative answer returns to DataScope. An affirmative (pressing "y", "Y" or Enter) exits. If the Control-C option is active in the Options Setup screen, pressing Control-C immediately performs the equivalent of Quit without a verification prompt. Esc MENU SELECTION: History Screen 1 of 1 Activate this menu selection to enter the History analysis of the current archive data file. The current archive file path specification is displayed in the main status screen. PgUp: Display a previous page of data up to the current first data byte. PgDn: Advance the display to the next page of data after the last byte. Home: Move the currently selected cursor to the first displayed data byte. End: Move the currently selected cursor to the last displayed data byte. Up arrow: Move the currently selected cursor up one line. Down arrow: Move the currently selected cursor down one line. Right arrow: Move the currently selected cursor right one data byte. Left arrow: Move the currently selected cursor left one data byte. F1: Calculate the effective baud rate for the selected data. F2: Specify com port restrictions for effective baud rate calculations. F9: Toggle the current cursor context for cursor motion and data searches. History sub-menu: Esc: Exit the History display; return to the display sub-menu. GoTo: Display captured data from a specific record number. Byte scan: Find next occurrence of a specific character (source sensitive). String match: Find the next occurrence of a string (source sensitive). Both Byte scan and String match search from the current archive location. Cursor: Alternate between the "a" and "b" time stamp cursors. MENU SELECTION: Capture Screen 1 of 1 Activate this menu selection to engage the live capture display. If the archive is active, the archive portion of the display will indicate the content of the archive file and the position of most recent archived data. If the archive is not active, the archive display will indicate the current captured contents of the archive file. The swing buffers indicate data filled sections with highlighted shading. MENU SELECTION: Single Screen 1 of 1 Activate this menu selection to engage a live, full screen, single port data monitor. The unselected port's data will be buffered but not displayed. The port of choice is the currently selected port as indicated by the main status display. MENU SELECTION: Dual Screen 1 of 1 Activate this menu selection to engage two live, half screen, independent data monitors. MENU SELECTION: Mixed Screen 1 of 1 Activate this menu selection to engage a live, full screen, dual port data monitor. Data from each port is displayed in-line, in order of appearance, without respect to the source. Source will be identifiable by virtue of the source attribute differences in the character display set. MENU SELECTION: Alternating Screen 1 of 1 Activate this menu selection to engage a live, full screen, dual port data monitor. Data from each port is displayed in order of appearance but separated by source onto independent lines. MENU SELECTION: Interactive Screen 1 of 1 Activate this menu selection to engage a live, full screen, dual port interactive data monitor. Data from each port is displayed in order of appearance, separated by source onto independent lines. In addition, keyboard and file output is transmitted from the currently selected port. The transmission data is displayed as though originating from the unselected port to allow easy distinction of sources. Normally, the unselected port will be inactive during interactive mode usage, but this is not required. 68 MENU SELECTION: Port Screen 1 of 1 Activate this menu selection to simply toggle the currently selected port. The current port is displayed in the top center of the main status screen. Esc MENU SELECTION: PathSpec Screen 1 of 1 Activate this menu selection to enter the Archive Setup screen and alter the archive file path specification, length and other archive parameters. Hot key = Alt-A. MENU SELECTION: Triggering Screen 1 of 1 Activate this menu selection to enter the Capture Mode Setup screen and alter capture mode triggering parameters. Hot key = Alt-C. 73 MENU SELECTION: Match (capture) Screen 1 of 1 Activate this menu selection to enable the capture mode where the trigger pattern is matched against the incoming port data to control the archiving process. Archiving will run in the background until the final trigger is received and the capture count is depleted. Hot key = Alt-M. MENU SELECTION: Freshen Screen 1 of 1 Activate this menu selection to start the normal archiving process running in the background (no matching) with an empty archive file. Hot key = Alt-F. This differs from the Enable entry which does not erase the contents of the archive file before initiating the archiving process. MENU SELECTION: Disable Screen 1 of 1 Activate this menu selection to disable the archiving process regardless of the means by which it was initiated. Hot key = Alt-D. MENU SELECTION: Enable Screen 1 of 1 Activate this menu selection to start the normal archiving process running in the background (no matching) without clearing the current data in the archive file. Any new data is appended to the old data as though the archive file had never been closed. Hot key = Alt-E. This entry differs from the Freshen selection which does clear the old data in the archive file before initiating the archiving process. NOTE: Enable archives the current contents of the swing buffers. 78 MENU SELECTION: Shell Screen 1 of 1 Activate this menu selection to generate a DOS shell for manipulating files or any other DOS activity. Return to DataScope by executing EXIT at the DOS prompt. Hot key = Alt-S. Esc MENU SELECTION: Ports Screen 1 of 1 Activate this menu selection to enter the Port Setup screen to allow configuration of uart parameters. Hot key = Alt-P. MENU SELECTION: Interrupts Screen 1 of 1 Activate this menu selection to enter the Interrupt Vector Setup screen which controls port base addresses and interrupt vector levels and installation. Hot key = Alt-V. MENU SELECTION: Translations Screen 1 of 1 Activate this menu selection to enter the Character Translation Editor and make changes to the port specific string representations of all possible character values. Hot key = Alt-T. MENU SELECTION: Kernels Screen 1 of 1 Activate this menu selection to enter the Kernel (configuration) setup screen to select from a list of pre-existing kernels or to build a new kernel storage file. Hot key = Alt-K. MENU SELECTION: Xmit files Screen 1 of 1 Activate this menu selection to enter the transmission file setup screen for the Interactive display mode. Specify the pathspec (Drive Letter, Path and Filename) for transmission during Interactive mode operation via the Insert key. Hot key = Alt-I. MENU SELECTION: Options Screen 1 of 1 Activate this menu selection to enter the Options Setup to set display and Control-C options. Hot key = Alt-O. 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 HISTORY MENU SELECTION: Esc Screen 1 of 1 Activate this menu selection to exit the History display and return to the Display sub-menu: Esc History Capture Single Dual Mixed Alternating Interactive Port HISTORY MENU SELECTION: GoTo Screen 1 of 1 Activate this menu entry to enter an edit screen for generating the new first display byte record number. Conclude entry with the Enter key to activate re-display at the newly specified record. Conclude entry with Esc to prevent a GoTo function and return to the original display. Number entry is in decimal, and the maximum allowable record number is displayed in the bottom line help box. HISTORY MENU SELECTION: Byte scan Screen 1 of 1 Activate this menu selection to enter an edit screen for generating the new character value (in the current base) of the next byte of interest in the archive file. Conclude entry with the Enter key to initiate the character scan and re-display at the next occurrence. Conclude entry with the Esc key to prevent a Byte Scan and return to the original display. Scans are not port dependent, so the current cursor selection is unimportant. For a port dependent scan use a single letter/character in the String match function. HISTORY MENU SELECTION: String match Screen 1 of 1 Activate this menu selection to enter an ascii string edit screen for the port sensitive match string. The currently selected cursor determines the source port. Conclude entry with the Enter key to initiate the string match and re-display at the next occurrence. Conclude entry with the Esc key to abort the function and return to the original display. At the conclusion of a successful match, the head of the source string will be displayed using the "a" cursor even if the "b" cursor is selected as the match source. Matching searches will wrap around the archive until one complete scan occurs without a match. Matching can be terminated at any time by striking any key. Port independent matches must use the one byte scan technique. HISTORY MENU SELECTION: Cursor Screen 1 of 1 Activate this menu selection to alternate between the "a" and "b" cursors. F9 keystrokes will also perform this identical function. CURSOR TIME ACCURACY The resolution of the cursor timing mechanism is +/- .84 microseconds. Due to the buffering nature of uarts, however, this timing accuracy can be misleading. The value of any given time stamp represents the moment at which the character is pulled from the uart by interrupt service routines, NOT the actual character arrival time. Consequently, it is impossible to indicate that two characters (on separate serial lines) have arrived simultaneously - there being a variable time skew due to interrupt service latency. The magnitude of this time skew is indicative of the service routine execution time and is highly influenced by processor speed. Generally, at lower baud rates and reasonable processor speed, skew is insignificant with respect to character length times. At higher baud rates (particularly 38,400 to 115,200) the effects of character simultaneity must be considered while measuring full duplex applications. For half-duplex and most (low duty cycle) full duplex applications, time stamps are highly accurate relative measures of character time distributions. For more information on recognizing when simultaneity is an issue, consult the user manual. HISTORY MENU SELECTION: Export Screen 1 of 1 Activate this menu selection to enter the Export Archive File parameter setup screen. 111 120 130 140 REVOLVING SELECTION Screen 1 of 1 You are editing a field containing a revolving list of predetermined values. These are the only legal values - no others are allowed. There are seven keys to operate the selection mechanism: Up arrow: Revolves upward in the list of items, wrapping around at the endpoint of the list. Down arrow: Revolves downward in the list of items, wrapping around at the endpoint of the list. Right arrow: Functions in exactly the same manner as the Up arrow cursor key. Left arrow: Functions in exactly the same manner as the Down arrow cursor key. Spacebar: Revolves the list in the upward direction only (with wrap-around, in exactly the same manner as Up and Left arrow cursor keys). Enter: Terminates selection, accepting the current list entry. Esc: Also terminates selection, accepting the current list entry. ALPHANUMERIC ENTRY Screen 1 of 1 All alphanumeric values are allowed in this string except nulls. Characters echo as single character graphical entities if not printable. Use the DOS Alt keypad entry method for values whose keyboard equivalent is unknown (hold the Alt key down while entering the numeric value on the keypad, and then release the Alt key to see the character equivalent). Take advantage of the nine editing keys which operate thusly: Home: Place the cursor at the start of the string. Tab: Clear (blank) the entire field and home the cursor. End: Place the cursor at the end of the string. Ins: Toggle the insert mode (an insert indicator will appear in the lower right hand corner of the screen if the insert mode is active). Del: Delete the character underneath the cursor. Right arrow: Move the cursor one character to the right. Left arrow: Move the cursor one character to the left. Backspace: Back up one character, remove it and drag the remainder of the string, if any. Enter: Accept the current string up to, but not including, the cursor. Esc: Accept the current string up to, but not including, the cursor. SINGLE DIGIT ENTRY Screen 1 of 1 PATHNAME ENTRY Screen 1 of 1 Pathnames do not include a filename. Direct path specifications and spec- ifications relative to the current directory are allowed. A direct pathname will begin with a backslash to denote its origin in the root directory. A trailing backslash is unnecessary but not prohibited. Relative pathnames can include deeper directory names and backslashes, but cannot begin with a backslash. Relative pathnames are relative to the current directory unless the environment contains the string PALS=path, which over- rides the current directory, resulting in the following hierarchy of path specifications: Direct paths override all alternative specification methods; Relative paths first attempt to find the environment variable PALS for a path specification; Failing to find PALS causes relative paths to use the current directory as a default. The only characters that are acceptable in pathnames are listed at the bottom of the entry screen. TWO DIGIT ENTRY Screen 1 of 1 Two digits are expected in this field. The current number base (set in the Character Translation Editor) dictates the range of allowable digits. Octal: 0 - 7. Decimal: 0 - 9. Hexadecimal: 0 - F. Home: Place the cursor at the start of the string. Tab: Clear (blank) the entire field and home the cursor. End: Place the cursor at the end of the string. Ins: Toggle the insert mode (an insert indicator will appear in the lower right hand corner of the screen if the insert mode is active). Del: Delete the character underneath the cursor. Right arrow: Move the cursor one character to the right. Left arrow: Move the cursor one character to the left. Backspace: Back up one character, remove it and drag the remainder of the string, if any. Enter: Accept the current number string. Esc: Accept the current number string. FILENAME ENTRY Screen 1 of 1 WARNING: Specification of a pre-existing file is not prevented. Be sure of your choices - use the file view function to select or preview filenames to be certain you do not overwrite a pre-existing file. Filenames can be eight characters long with a three character extension. You must specify an extension if one is desired (there is no default or forced extension). You can use any name and extension that is not in conflict with operating system restrictions. Home: Place the cursor at the start of the string. Tab: Clear (blank) the entire field and home the cursor. End: Place the cursor at the end of the string. Ins: Toggle the insert mode (an insert indicator will appear in the lower right hand corner of the screen if the insert mode is active). Del: Delete the character underneath the cursor. Right arrow: Move the cursor one character to the right. Left arrow: Move the cursor one character to the left. Backspace: Back up one character, remove it and drag the remainder of the string, if any. Enter: Accept the current string. Esc: Accept the current string. BASE DEPENDENT NUMERIC ENTRY Screen 1 of 1 Up to three or four digits are expected here. Leading zeroes are acceptable but not necessary. The current number base (defined in the Character Trans- lation Editor) will determine the valid entry digit range except in the case of port base address entry (which is always in hexadecimal). Octal: 0 - 7. Decimal: 0 - 9. Hexadecimal: 0 - F. Home: Place the cursor at the start of the string. Tab: Clear (blank) the entire field and home the cursor. End: Place the cursor at the end of the string. Ins: Toggle the insert mode (an insert indicator will appear in the lower right hand corner of the screen if the insert mode is active). Del: Delete the character underneath the cursor. Right arrow: Move the cursor one character to the right. Left arrow: Move the cursor one character to the left. Backspace: Back up one character, remove it and drag the remainder of the string, if any. Enter: Accept the current number string. Esc: Accept the current number string. DRIVE LETTER ENTRY Screen 1 of 1 A single letter (upper or lower case) is expected here. It will always be necessary to backspace or press the Home key before input will be accepted. Any valid DOS drive letter from A through Z will be accepted. Home: Place the cursor at the start of the string. Tab: Clear (blank) the entire field and home the cursor. End: Place the cursor at the end of the string. Ins: Toggle the insert mode (an insert indicator will appear in the lower right hand corner of the screen if the insert mode is active). Del: Delete the character underneath the cursor. Right arrow: Move the cursor one character to the right. Left arrow: Move the cursor one character to the left. Backspace: Back up one character, remove it and drag the remainder of the string, if any. Enter: Accept the current string. Esc: Accept the current string. SINGLE DECIMAL DIGIT ENTRY Screen 1 of 1 Enter a single decimal digit (regardless of the current number base) to set the number of minutes before the screen saver blanks the screen. A value of zero will disable the screen saver feature. Live displays (Capture, Single, Dual, Mixed, Alternating, and Interactive) are not blanked by the screen saver. All other displays, status and help screens are blanked when the screen saver timer expires. EXTENSION FILTER ENTRY Screen 1 of 1 One to three letters are expected here to designate the file Extension Filter which will determine the filenames displayed in the file library/selection utility. Wildcard characters ("*" and "?") are valid to allow a broad range of file extensions. The normal "." preceding an extension is implied and cannot be entered. Home: Place the cursor at the start of the string. Tab: Clear (blank) the entire field and home the cursor. End: Place the cursor at the end of the string. Ins: Toggle the insert mode (an insert indicator will appear in the lower right hand corner of the screen if the insert mode is active). Del: Delete the character underneath the cursor. Right arrow: Move the cursor one character to the right. Left arrow: Move the cursor one character to the left.

Esc: Accept the current string up to, but not including, the cursor. 160 HYBRID STRING ENTRY Screen 1 of 1 Two methods of entry are available to specify a capture/search string, corresponding to the two entry fields. Press the up or down arrow keys to select a field. Cursor presence indicates current field selection. Lower (string) field: Normal keystroke depressions and Alt/numeric combin- ations enter all character values except nulls and carriage returns. Upper (numeric) field: Numeric entries in the proper (indicated) base can be edited into this field whenever the cursor is present. Pressing Enter while in this field will add the current numerical field value to the string at the current string cursor position (as long as the numerical value is valid). Press Esc to exit this field (or the down arrow). Home: Place the cursor at the start of the field. Tab: Clear (blank) the entire field and home the cursor. End: Place the cursor at the end of the field. Ins: Toggle the insert mode (an insert indicator will appear in the lower right hand corner of the screen if the insert mode is active). Del: Delete the character (or numeral) underneath the cursor. Right arrow: Move the cursor one character to the right. Left arrow: Move the cursor one character to the left. Backspace: Remove the previous character and drag any remaining characters. Enter: Accept the current string edit or inject the numeric field into the string field at the cursor location (depending upon the selected field). Esc: Accept the current string up to, but not including, the cursor. EXPORT FILE SIZE LIMIT Screen 1 of 1 File size is expressed in Kilobytes.
