In general, the commands used here are the same two-letter mnemonic commands used in Crosstalk XVI; if you press the down-arrow key you can read through some get-started suggestions and a list of Crosstalk commands you can use. If you wish to make a call, command "HELP CALL". If you wish to exit from Crosstalk, command "QUIT". Here is a list of Crosstalk keyboard commands, arranged by function groups: For help on any specific command, command "HELP command". You must use at least the first two letters of the command, like "HE AC" to get help on the ACcept command. Communications parameter settings: ACcept ANswerback APrefix AWrap DAtabits DPrefix DSuffix DUplex FIlter FLow HAndshake INfilter LBreak LFauto MOde NAme NUmber OUtfilter PArity PMode POrt PWord SPeed STop Terminal emulation: EMulate Key settings: ATtention BReak COmmand FKey SWitch TKey TUrnaround General Crosstalk operations: CApture CDir CLear CStat DEbug DIr DO DRive EDit EPath ERase GO HElp LIst LOad PIcture PRinter QUit RDdials RUn RVue SAve SCreen SNapshot SStep SUmmary SXisting TErminate TImer TYpe UConly VIdeo WHen WRite XDos X4 (Mk.4 eXec) Text transfer setup: BLankex CWait LWait TAbex Text file transfer execution: SEnd Protocol (binary) file transfer setup: BKsize KErmit MAxerrs PCol PMode XType Protocol (binary) file transfer execution: XTALK protocol: RQuest RCeive XMit XMODEM protocol: RXmodem XXmodem Kermit protocol: GKermit RKermit XKermit Dart protocol: RR XR ZMODEM protocol: RZmodem XZmodem For help on any specific command, command "HELP command".

Use the NUmber command to set the phone number you want to call. 2. Select a modem speed with the SPeed command. 3. Command "GO" at Crosstalk's "Command ?" prompt. 4. Crosstalk will dial the call, and alert you when the connection is made. 5. To disconnect, press ESC, then command "BYE" at the "Command ?" prompt. ~End ~B AB ~K AL,AS,LA,IF,JU,SK,ME,RW,SB,WH This command is only appropriate when used in a script file. See your manual for details. ~End ~B AC ACcept [Nothing | Appends | Creates | Everything] The ACCEPT command allows you to set the type of access a caller has when calling into an answering Crosstalk system. By setting the access level, you can protect your system. The options to the ACCEPT command are: Option Action -------- ------ Nothing - Prohibit caller from writing to any files Appends - Allows caller to append captured data to an existing file, but not to create any new files. Creates - Allows caller to append data to or create new files, but not to overwrite existing files. Everything - Allows caller full access to system. This is the default. ~End ~B AN ANswerback [ON | OFF] The ANSWERBACK command tells Crosstalk whether or not to respond to a received ^E character. Many computer networks utilize this feature as a means of identifying a caller. Answering Crosstalk and Transporter systems use this to request your password. If ANSWBACK is ON, a received ^E will cause the contents of your F4 key (see FK command) to be sent. If ANSWBACK is OFF, the ^E will be ignored. ~End ~B AP APrefix <string> The APREFIX command tells Crosstalk how to make your modem answer the phone. When you place Crosstalk in answer mode, the string set by APREFIX is sent to the modem. By changing the APREFIX string, you can change the number of times the phone will ring before Crosstalk answers. See your modem manual for specific commands for your modem. ~End ~B AT ATtention [<key_scan_code>] The ATTENTION command selects the key to be used for the "ATTENTION" key. The attention key is the key used to display Crosstalk's "Command?" prompt when you are in terminal mode. Note that this key can not be sent to the remote computer, since typing it causes Crosstalk immediately to enter the command mode. The ESCAPE key is the default ATTENTION key. If the system you are calling requires you to send an ESCAPE, select another key for the attention key. ~End ~B AW AWrap [ON | OFF] The AWRAP command tells Crosstalk whether it should wrap the cursor at the 80th column when emulating a DEC VT-100 or 3.64 ANSI terminal. ~End ~B BK BKsize <integer> The BKSIZE command sets the size of the data block (in 256 byte increments) sent during XTALK protocol transfers. It defaults to 1. If you are "direct connecting" two computers together without modems, you may wish to select a larger block size (up to 16) since this marginally speeds up protocol transfers. We recommend the default setting when transferring files via modems. ~End ~B BL BLankex [ON | OFF] The BLANKEX command tells Crosstalk how to handle "blank" lines when sending files to another computer with the SEND command. If BLANKEX is ON, Crosstalk will convert blank lines into lines consisting of one space. This may be useful when sending prepared text containing empty lines into a host computer system which assumes a blank line to mean "end of text". ~End ~B BR BReak [<key_scan_code>] The BREAK command is used to select the key to be used for sending a break. The END key is the default BREAK key. ~End ~B BY BYe The BYE command hangs up the phone line, and disconnects the current call. Use this command when you wish to hang up and make another call without exiting Crosstalk. ~End ~B CA CApture [ON | OFF | <filename> [/E | /A] | <lines ] The CAPTURE command captures directly to disk, using a default filename if you do not specify "CA filename". If the file already exists, Crosstalk will append the new data to the end of the old file. The command "CA OFF" will end the capturing process and close the capture file. When used with a file name, the /E switch causes Crosstalk to erase any old file of the same name when it begins to capture. The /A switch tells Crosstalk to append the newly captured material to the old file. If you wish to capture some data which is already on your screen, and capture is OFF, you may use the "RETRO-CAPTURE" feature. Command "CA <" and Crosstalk will retroactively capture the data on the screen, add it to the capture file, and leave CAPTURE ON. ~End ~B CD CDir [<directory_name>] The CDIR command allows you to switch disk directories. The command "CD" alone will show the name of the current directory. ~End ~B CL CLear The CLear command clears the terminal window if you are looking at the terminal screen; if you're looking at the status screen it clears the information window on the lower part of the screen. ~End ~B CO COmmand <key_stroke_value> The COMMAND command sets the COMMAND key. The COmmand character is the key a caller would type if he had called into your system and wanted to enter commands to Crosstalk. We recommend that you leave this key set to the default setting of ^C. ~End ~B CS CStat The CSTAT command displays the status of the capture file - how much text has been captured, and how much space is left on the current disk. ~End ~B CW CWait [None | Echo | Delay <integer>] The CWAIT command tells Crosstalk how to wait between characters when transmitting files with the SEnd command. Use this command when you are sending text to a computer system which can not accept a whole line of text at full speed. The CWAIT command has several options. The chart below illustrates the effect of each: Option Effect ------ ------ NONE Do not wait at all ECHO Wait for each character to be echoed by the host before sending the next character. DELAY XX Delay xx thousandths of seconds, then send the next character. Note that CWAIT can be used in combination with LWAIT to allow you to transmit text slowly enough for virtually any dial-up computer system. ~End ~B DA DAta [7 | 8] The DATA command is used to select the number of data bits used by Crosstalk. The default value is 8. Crosstalk automatically switches to 8 bits whenever a protocol transfer is performed, even if 7 bits had previously been selected. ~End ~B DE Debug [Off | Hex | Ascii | Char | RS232] The DEBUG command allows you to select one of four "debug" modes. The debug modes allow you to display incoming control-characters graphically on your screen. This is often useful when attempting to identify non-printing control characters transmitted by some dial-up computer systems. The chart below shows how each of the debug modes operates: Mode Action ---- ------ Off Incoming control characters are not altered. Hex All incoming characters are shown as hex numbers. For example, an incoming ^Z will be shown as [1A]. ASCII Incoming control-characters are shown by their ASCII mnemonics. For example, and incoming ^Z will be shown as [SUB]. Char Incoming control-characters are shown in the form [^X]. RS232 This option is not available in this version of Crosstalk. ~End ~B DI DIr [<filespec>] The DIR command is used to view the disk directory, much like the DOS "DIR" command. Like the DOS DIR command, you may provide an optional file name, and the program will display only those files given in the file name. For example, the command "DIR .ASM" will show only the .ASM files. XVI/4 uses the Crosstalk Mk.4 directory display. ~End ~B DN This command is not used by XVI/4. ~End ~B DO DO [<script_name>] The DO command instructs Crosstalk to perform the commands contained in a "script" file. Script files are files containing commands for Crosstalk to perform. There are three forms of the DO command. The table below shows how each works. Command Action: ------- ------- DO When no other script file is active, this command will display a menu of the available script files, and then ask you to choose one. The chosen file will then be performed. DO If a script file has been suspended, commanding "DO" will resume the suspended script file. DO BERT Performs the commands contained in the script file "BERT.XTS". You may create a script file with any text editor, such as the EDLIN program which is included with DOS. Script files must have the file name extension "XTS". The script files may contain any commands you wish Crosstalk to do. There are two commands which are especially useful in script files: the "REply" and "WAit" commands. ~End ~B DP DPrefix <string> The DPREFIX command tells Crosstalk how to dial your modem. When you instruct Crosstalk to dial, the program sends the following data to the modem: DPREFIX string | NUMBER string | DSUFFIX string By changing the DPREFIX string, Crosstalk can dial a number of different types of auto-dial modems. There are several characters which have special meaning when placed in a DPREFIX string. These are: Character Effect ---------- ------ | Places a carriage return (ENTER key) in the string. ~ Causes Crosstalk to delay one second when sending the dialing commands to the modem. ^ The character following the ^ character is sent as a control character. For example, "^T" would place the ^T character in the dial prefix. ~End ~B DR DRive [<drive_letter>] The DRIVE command has two functions. Commanding "DRIVE" alone will show you the amount of space remaining on all of the drives in your system. Commanding "DR" followed by a drive name ("DR B:") will change the "default" drive to the specified drive. ~End ~B DS DSuffix <string> The DSUFFIX command sets the dialing suffix string. (see explanation of the DPREFIX command). The same special characters apply to DSUFFIX as apply to DPREFIX. ~End ~B DU DUplex [Full | Half] The DUPLEX command sets duplex to full (local echo OFF) or half (local echo ON). Most dial-up computer systems require that your system be set for FULL duplex. Note that when you select ANSWER mode, Crosstalk selects HALF duplex. When you select CALL mode, the program automatically selects FULL duplex. See the glossary for an explanation of "duplex". ~End ~B ED EDit <filename> The EDIT command allows you to run a text editor from within Crosstalk. When you use the EDIT command, Crosstalk stays in your computer's memory, and continues to receive any incoming data. After you exit from your text editor, you will automatically return to Crosstalk. If you have set up a path to your editor with the EPATH command, the EDIT command will use your editor; otherwise it will use Crosstalk Mk.4's internal editor. ~End ~B EM EMulate [None | Vt-100 | 52 | Televideo | Adds | Ibm-3101 | 3.64 ANSI] The EMULATE command sets the type of terminal Crosstalk will emulate. This is important to you only if the system you are calling utilizes cursor positioning and clear screen codes for a particular type of terminal. The terminals Crosstalk can emulate are: Televideo 910/920, IBM 3101, ADDS Viewpoint, DEC VT-52, DEC VT-100, and the ANSI 3.64 color terminal used by many BBS systems. To select an emulation mode, command "EM x", where x is the first letter of the terminal you wish to emulate. ~End ~B EN The END command is used to end a script. For more information please see your manual. ~End ~B EP EPath <pathname\progname> The EPATH command is used to tell Crosstalk where to find your text editor program. Before Crosstalk can run your text editor for you, it has to know where to find the editor, and what the name of the editor is. For example, if you wish to use the EDLIN editor supplied with DOS, and EDLIN.COM is in a subdirectory called "\bin", then you would command: EPATH C:\BIN\EDLIN.COM We suggest that you set EPATH once, then save a new STD file, so that you won't have to re-enter the editor name each time you run Crosstalk. ~End ~B ER ERase <filespec> The ERASE command erases files from your disk like the DOS DEL command. You will be asked to confirm an erase before the operation actually takes place if you use a wildcard filespec. The command "ER *.*" will allow you to selectively erase any or all files on a disk. Note that an answer-mode caller may NOT erase files from the disk. ~End ~B FI FIlter The FILTER command is used to select which characters Crosstalk will discard when the INfilter option is used. Command "FI" and press ENTER, and Crosstalk will show you a list of allowable control characters. You may change the list as desired for your application. Note that the FILTER settings are saved when a command file is saved with the SAVE command. ~End ~B FK FKey [<keyspec> <key_contents>] The FKEY command is used to set and display the contents of the programmable function keys. The command "FK" will show the settings of the "normal" function keys, "FK A" will show the contents of the "Alt" functions keys. The other two sets of keys are "Shift" and "Control". To set a function key, command "FK n string" (or "FK An string" for alt-keys, etc.) where n is the number of the key to be set (1-10, S1-S10, C1-C10, A1-A10) and "string" is the string of text assigned to that key. Several characters have special meaning when used in function keys: Character Meaning --------- ------- | Places a carriage return (ENTER key) in the string. @ Indicates this is a command to Crosstalk XVI; the at-sign must be the first character in the key contents. For example, the command "FK C1 @PR /|" will set key control-F1 to "@PR /|". When you press Control-F1 Crosstalk will toggle the printer on or off. ~End ~B FL The FLOW command is used to tell Crosstalk how to control character flow with the host computer system. Normally, FLOW is set to ^S/^Q, meaning that the host system will stop sending upon receipt of a ^S, and will re-start after receiving a ^Q. To enter a new set of stop/start characters, command: "FLOW a/b", where a and b are as follows: a Sent by host to make Crosstalk stop sending and sent by Crosstalk to make the host stop sending b Sent by host to let Crosstalk start sending again and sent by Crosstalk to let the host start sending again For example, the command: "Flow S/Q" will set ^S as the stop character, and ^Q as the restart character. To disable software flow control entirely, command "FLOW -". See also "HAndshak." ~End ~B GK GKermit <filespec> The GKermit command is used to "get" files from a Kermit Server. Crosstalk will request the specified files from the server, and begin waiting for the files to arrive. If no such files exist on the server, the message "no files" will be displayed. ~End ~B GO GO [Local] The function of the GO command depends on which mode the program is in. In CALL mode, The GO command tells Crosstalk to dial a number and establish a connection. You may instruct the program to re-dial automatically if a connection is not established on the first try. The command "GO R 30" would tell Crosstalk to re-dial every 30 seconds until a connection is established. The command "GO LOCAL" tells Crosstalk that there is no modem connected to the system or just to "talk" to whatever is connected to the port specified. Use this option to "talk" to the modem or when using Crosstalk to communicate between two computers "hard-wired" together. When the local option is used, the carrier detect (CD) signal on the RS-232 interface is ignored. In ANSWER mode, the GO command tells Crosstalk to begin waiting for incoming calls. ~End ~B HA HAndshak [ON | OFF] The HAndshake command tells Crosstalk to observe or ignore the hardware "handshake" lines on pins 4 and 5 (RTS and CTS). If Handshake is OFF, the signals on these lines are ignored. ~End ~B HE HElp <topic> The HELP command provides help on all of Crosstalk's commands. Commanding "HE" with no option displays a list of all of Crosstalk's commands. If you need help with a command, type "HE XX" <CR>, where "XX" is the command you need help with. If Crosstalk asks you a question you don't understand, enter a "?", and the help for that command will be displayed. ~End ~B HK This command is not used by XVI/4. ~End ~B IN INfilter [ON | OFF] The INFILTER command tells Crosstalk to discard incoming control characters when in terminal mode, and to strip the high bit from the characters in the incoming data stream. The stripping action is only in effect in terminal mode, and does not affect protocol file transfers. Some host computer systems may send control characters which are meaningless to the your computer. Turning INFILTER ON will discard these characters. If your see extraneous "junk" characters on the terminal screen, try turning INFILTER ON. INfilter also "strips" the high bit off from 8-bit characters. With INFILTER OFF, these characters may appear as "graphics" characters. Turning INFILTER ON will display these characters as text. ~End ~B KE The KERMIT command allows you to control KERMIT file transfers. Most Kermit commands require two options; for example, "KERMIT TIMEOUT 20". The KERMIT commands are: Get - Get files from Kermit server (same as GK command) Send - Send files to another Kermit program (same as XK command) Receive - Receive files from Kermit non-server (same as RK command) Hchar - Set Header character (must be a printable char.) Eol - Set Kermit End-of-line character (must be a printable char.) Timeout - Set Kermit "timeout" interval Psize - Set Kermit packet size (must be 10-94) Wsize - Set sliding window size (must be 1-31) Ytime - Set delay time per packet in milliseconds (must be 0-1000) CQuote - Set Kermit control quoting character (must be a printable char.) BQuote - Set Kermit binary quoting character (must be a printable char.) Ichar - Set optional iteration character (must be a printable char.) DataChk - Set Kermit Data check method: 1 = 8 bit checksum 2 = 16 bit checksum 3 = 16 bit CRC List - List current Kermit settings Finish - Finish Kermit server session Mode - Text or Binary file mode: BINARY mode will send the file "as is," while TEXT mode only sends ASCII characters and terminates on ^Z. ~End ~B LB LBreak <integer> The LBreak command allows you to set the duration or Length of the Break signal. The rate is in thousandths of a second and must be between 10 and 8000 (.010 second to 8 seconds). The default is 200 milliseconds (.2 seconds). ~End ~B LF LFauto [ON | OFF] When LFAUTO is ON, Crosstalk will print a line feed on the screen after each received carriage return. This is useful when communicating with systems which do not send line feeds. Also, when LFAUTO is ON, Crosstalk will print a carriage return each time a line feed is received. This is useful when communicating with systems which send line feeds without carriage returns. ~End ~B LI LIst The LIST command is used to display Crosstalk's parameter settings. The operation of the LIST command depends on who issued the command. If "LI" is entered as a command from the status screen, several infrequently-used parameters are shown in the status screen "window". If a person calling into an answer-mode Crosstalk system issues the LIST command, the program displays the full listing of all the parameters, in much the same format as it is displayed on the status screen. ~End ~B LO LO [<command_file_name>] The LOAD command is used to load Crosstalk command files. Command files are files containing commands for Crosstalk to perform. The command "LO" will display all of the available command files, and allow you to choose one to load. The command "LO FRED" will load in "FRED.XTK", and perform all of the commands contained in that file. ~End ~B LW LWait [None | Prompt | Char <quoted_literal> | Delay <integer> | ... Echo | Quiet | Manual] The LWAIT command tells Crosstalk how to wait between lines when transmitting text files with the SEnd command. There are several options to the LWAIT command. The table below shows how each option works: Option Effect ------- ------ None Each line is sent with no waiting. Prompt X Send a line of text, wait for a prompt of X characters, then send the next line. Char "X" Send a line of text, wait until the character "X" is received, then send the next line. Delay X Wait X tenths of seconds between lines. Echo Wait until a carriage return is echoed from the host system. Quiet X Wait until the line is "quiet" (i.e., no characters received) for X tenths of a second, then send the next line. Manual Send a line of the file, then wait for a key from the user before sending the next line. ~End ~B MA MAxerrs <integer> The MAXERRS command allows the user to set the maximum number of consecutive errors allowed during a CROSSTALK, KERMIT, or XMODEM protocol transfer. If this limit is exceeded, the transfer is aborted. ~End ~B MO MOde [Call | Answer] The MODE command tells your Crosstalk program whether to Make or Answer calls. If you wish to MAKE a call, select "CALL" mode. To ANSWER calls, use "ANSWER" mode. Crosstalk automatically selects HALF Duplex (see DUplex command) when the answer mode is selected, and selects FULL duplex when call mode is selected. ~End ~B NA NAme <string> The NAME command is used to set the name of a called location. Use of this command is optional. The NAme has no function in call mode. In answer mode, the NAme will be sent as a "greeting" message whenever a remote terminal calls into Crosstalk. ~End ~B NO This command is used internally between two Crosstalk systems. It is sent from an answer system to a call system at the end of a file transfer, to tell the calling system that there are no more files to be transmitted. ~End ~B NU NUmber <phone_number> The NUMBER command sets the phone number to be dialed. The number may be up to 38 characters long. There are several characters which have special meaning when used in a phone number. Consult your modem manual for a full list of these characters. ~End ~B OU OUtfilter [ON | OFF] The OUTFILTER command instructs Crosstalk to screen out line feed when sending text files with the SEnd command. If OUTFILTER is ON, line feeds characters are discarded. ~End ~B PA PArity [None | Odd | Even] The PARITY command is used to set the parity bit to the appropriate value. Some systems require that parity be set correctly, other systems ignore parity entirely. The possible settings for the PARITY command are None, Even, and Odd. ~End ~B PC PCol [DArt | XTalk | XModem | KErmit | CServe b | ZModem] The ProtoCol command (PC) is used to select a protocol, especially when the protocol desired is not a "native" Crosstalk XVI protocol. The native Crosstalk XVI protocols have unique commands for sending and requesting/receiving files (see RK, GK and XK for Kermit, RQ and XM for Crosstalk protocol, and RX and XX for XMODEM protocol.) Similarly, the Crosstalk Mk.4 protocols used by XVI/4 have new, Crosstalk-XVI-like but non-Crosstalk-XVI-compatible file transfer commands (RR and XR for DART, RZ and XZ for ZMODEM). The CompuServe B protocol (CServeB), which is controlled by the host and has no local transfer commands, must be explicitly loaded (with the PC CS command) when you are in CALL mode. ZMODEM should also be loaded before use, in CALL mode, with the PC ZM command. ZMODEM is usually host-controlled, but implementations vary. When a caller connects with your system, however, the caller must use the PCol command explicitly to specify the protocol he wishes to use if it is not XTALK, XMODEM, or Kermit. Using the PC command in other cases is not harmful, and making it a rule to use it in all cases might make life easier if you use lots of different protocols with various hosts. Protocol Load Protocol Transfer to you Transfer to host -------- ------------- --------------- ---------------- XTALK PCol XTalk RQuest XMit XMODEM PCol XModem RXmodem XXmodem Kermit PCol KErmit GKermit, RKermit XKermit DART PCol DArt RR XR ZMODEM PCol ZModem RZmodem XZmodem CServeB PCol CServeb (host controlled) (host controlled) The appropriate transfer command should be followed by the name of the file(s) to be transferred. When calling CompuServe, the PC CS command enables the CompuServe B protocol, which is then controlled by the host computer. When XVI/4 is in Answer mode, a caller using Crosstalk Mk.4 can send the command PC DA to the answering XVI/4 to enable the DART protocol. DART is the preferred protocol for file transfers between XVI/4 and Crosstalk Mk.4 systems. ~End ~B PI PIcture <filename> The PICTURE command allows you to take a "picture" of the screen, and save the picture into a disk file of your choice. For example, the command: PICTURE BERT will save an image of the screen in the file BERT. If BERT already exists, the program will erase the old file. To add the new picture to the end of the file, use the "/A" option: PICTURE BERT /A The PICTURE command is most useful when you need to make an absolute copy of the screen. All of the data on the screen is saved in the file exactly as it appears on the screen. ~End ~B PO POrt [1 | 2 | 3 | 4] The PORT command tells Crosstalk which of the computer's communications ports to use. Note that on some computers, it may be necessary to re-set the baud rate after switching ports. The number of ports available depend on how many ports are installed in your computer. ~End ~B PM PMode [1 | 2] The PMODE command tells Crosstalk what type of system you are transferring files with. If you are sending files to another MS-DOS or PC-DOS system, set PMODE to 2; if you are sending files to a CP/M system, set PMODE to 1. ~End ~B PR PRinter [ON | OFF] The PRINTER command tells Crosstalk to echo all data displayed on the terminal screen to the printer. Turning PRINTER ON does not turn the terminal video display off. The command "PR /" will toggle the printer to the opposite state of what it currently is. Crosstalk Mk.4 does all its printing through DOS, so XVI/4's PRinter DOS command is equivalent to PRinter ON. ~End ~B PW PWord <caller_password> The PWORD command is used to set Crosstalk's answer password. The password may be up to 12 characters long. If you have set a password, then any person calling into your system will be required to enter the password before gaining access to your system. Use PW '' to disable the password feature. ~End ~B QU QUit The QUIT command tells Crosstalk to disconnect any call in progress and return to DOS. A shortened version of this command, just the letter Q, will end XVI/4 and give you the Crosstalk Mk.4 command line. ~End ~B RC This command is used internally by Crosstalk during file transfers. ~End ~B RD RDials <integer> The RDIALS command tells Crosstalk how many times to dial a phone number before abandoning the call. The normal value is 10. If you set RDIALS to zero Crosstalk will not attempt to re-dial a call if the call fails to connect on the first try. ~End ~B RE REply <string> The REPLY command sends a string of text to the modem. The command "RE Hello" would send the text "Hello" to the modem. If the modem is connected to another modem, the test will be relayed to the distant computer as it you had typed it. To send a control character, enter the character in the form "^X". To send a carriage return, use the vertical bar "|". The REply command is normally used only in a Crosstalk script. Scripts are special files which contain commands for Crosstalk to perform. ~End ~B RK RKermit <filename> The RKERMIT command is used to receive files from another computer system using the KERMIT protocol. To transfer a file from another KERMIT system to yours, tell the other system to begin sending the files, then press the attention key and command "RK". ~End ~B RQ RQ <filename> The RQUEST command is used to request a transfer of files from another Crosstalk system. This command should only be issued from a CALL mode system when calling into an ANSWER mode system. You may specify an optional target or destination drive name when issuing the RQUEST command. Some examples of this are shown below: Command Result ------- ------ RQ *.asm Request all files with the type .ASM RQ B:FRED Request the file FRED from drive B:, place the file on the default drive. RQ B:BERT C: Request the file BERT from drive B:, place the file on drive C:. ~End ~B RR RR <filespec> The RR command is used to request files from a Crosstalk Mk.4 host using DART protocol. To transfer a file or group of files from the distant system to yours, press the attention key and command "RR <filespec>". Commanding RR *.* on your system, while communicating with a Crosstalk Mk.4 host using the DART protocol, will download all the files in the current directory on the distant system to your system. ~End ~B RU RUn [[/] <progname>] The RUN command is used to run other programs from Crosstalk (DOS 2.0 & later ONLY). To run another program, command "RUN (name)". Crosstalk will turn control over to the other program, and control will return to Crosstalk when the second program is finished. You may also temporarily return to DOS by commanding "RUN" with no program name. Once you are at the DOS level, you may run another program. To return to Crosstalk, enter "EXIT" at the DOS prompt. Entering a / character between RUN and the command you wish to execute will cause Crosstalk to bypass the "Press space bar..." message when the other program is finished. ~End ~B RV RView The REVIEW command (RV) allows you access to Crosstalk Mk.4's review buffer, showing you the text that has scrolled off your terminal screen. Once in the buffer, you may use the arrow keys, PgUp, PgDn, and other standard cursor/text movement keys to review the text. Press the ATTENTION key (defaults to ESCape) to leave the review buffer or for other Review options. ~End ~B RX RXmodem <filename> The RXMODEM command is used to receive files from another computer system using the XMODEM protocol. To transfer a file from another system to yours, first tell the other computer to send you a file, then press the attention key and command "RX <filename>". The type of XMODEM transfer used depends upon the setting of XType. You may override the XType setting with a command line option: RX <filename> /mode, where mode may be: SUM = original XMODEM protocol with checksum error detection CRC = normal XMODEM protocol with 16-bit CRC error detection K = large blocks (1K) sent with 16-bit CRC error detection G = Go mode, no error detection (assumes error-free link) For instance, to force CRC mode, use "RX <filename> /CRC". ~End ~B RZ RZ <filespec> The RZ command is used to request or receive files from a host using ZMODEM protocol. To transfer a file or group of files from the distant system to yours, make sure the host is ready to send the files, then press the attention key and command "RZ <filespec>". ~End ~B SA SAve <command_file_name> The SAVE command saves a Crosstalk command file for future use. All of Crosstalk's operating parameters, including all function key definitions and screen colors are, saved in the command file. ~End ~B SC The SCREEN command has two purposes: It may be used to switch screens under control of a script file, or it may be used to select the colors to be used. Some typical SCREEN commands are: Command Effect -------- ------ SC S Switch to STATUS screen display SC T Switch to TERMINAL screen display SC N y Set "normal" screen color to dark yellow. SC H G Set "highlighted" screen color to bright green SC L w Set status line color to white. ~End ~B SE ~K READ ~K UPLOAD Use the SEND command to send a text file from your disk to another computer system. This command is most often used when communicating with another computer which is not running Crosstalk. If the system you are communicating with is running Crosstalk, use the "XMit" command instead. Several other commands are used to modify the method the SEND command uses to send files. For information on all of the commands affecting the operation of the SEND command, see the LWAIT, CWAIT, BLANKEX, and OUTFILTER commands. ~End ~B SE SEnd <filename> The SEND command is used to "demon type" a file to a host system, using the LWait and CWait parameters to control the speed of the transfer. This allows you to create text off-line with your local text editor and transfer it to a host's text receptor (usually an editor) as if you were typing the text online. ~End ~B SN SNap [24] The SNAPSHOT command is used to take or review a "snapshot" of the terminal screen; the snapshot is saved in the file XVI$SNAP.$$$. Command "SN 24" to take a snapshot of all 24 lines on the screen. You may then view this screen, as saved in XVI$SNAP.$$$ by typing "SN" alone. This is especially useful when trying to remember a long list of menu items on a screen. The snapshot file remains intact until you take another snapshot. ~End ~B SP SPeed <modem_speed> The SPEED command selects the speed at which your computer will communicate over the phone line. The first two digits of the desired speed need must be entered. Note that 110 baud is "0110". ~End ~B SS SStep <script_name> The SSTEP command, like the DO command, executes a script file, but before each line is executed, it is displayed on the command line. The line will begin with "S:", and pressing any key will execute that command. You can also press: G for go, discontinuing single step mode. Useful for continuing once you've found your bug. I for ignore, don't execute this command, skip to the next command and continue single stepping ~End ~B ST STop [1 | 2] The STOP command sets the number of stop bits used to make up the data word. Most systems use 1 stop bit at speeds of 300 baud and above, and 2 stop bits at 110 baud. ~End ~B SU SUmmary [ON | OFF] The SUMMARY command will allow CROSSTALK to keep a log of all calls made. The file, called XTALK.LOG, will record the date, time, and length of any calls placed or answered, and other information. ~End ~B SW SWitch <key_stroke_value> The SWITCH command selects the key to be used for switching between the terminal and status screens. This key is normally the HOME key, but can be changed to another key if desired. ~End ~B SX SXisting The new-with-XVI/4 SXisting command takes the existing parameters as set in Crosstalk Mk.4, converts those settings to their XVI/4 analogues, and saves them in the XVI/4 command file STD.XTK. The primary use of this command is internal within XVI/4; it's used if you have no STD.XTK when you start XVI/4. ~End ~B TA TAbex [ON | OFF] The TABEX command is used to turn tab expansion on and off. When TABEX is on, tab characters are sent as spaces to the next tab position. This is useful when sending files to systems which do not interpret tabs correctly. Note that the TABEX command only affects the SEND command. It has no effect on normal "terminal mode" operation, and does not affect the file on your disk. ~End ~B TE This command is not supported in this version of Crosstalk. ~End ~B TI TImer [ON | OFF] The TIMER command allows you to disable the "online" timer on the terminal screen. When TIMER is ON, the online connection time is constantly displayed at the lower right corner of the screen. Setting TIMER to OFF removes the timer count from the screen. Note that the timer does not count unless the TIMER command is set to ON, and that the timer may not be displayed under some circumstances or certain terminal emulations. ~End ~B TK TKey [ON | OFF] The TKey command tells CROSSTALK to use either the terminal emulation function key definitions or the user defined function key definitions when emulating a DEC VT-100 or IBM 3101 terminal. With TKey ON, the terminal emulator function keys are used. With TKey OFF, the user defined key definitions are used. ~End ~B TU TUrnaround <key_stroke_value> Some computer systems use a key other than ENTER to mean "end of line". The TURNAROUND command tells Crosstalk which character to send when the ENTER key is pressed. ~End ~B TY TYpe [<filename>] The TYPE command is used to view the contents of a disk file; the file is simply scrolled across the screen This version of Crosstalk does not support the TY command's # option to show line numbers in the file. You may also use Crosstalk Mk.4's BROWSER to display files, by using the command X4 BROWSE <filename> The TYpe command without a file name argument puts you in Crosstalk Mk.4's review buffer. For more information, see the RV command. ~End ~B UC UConly [ON | OFF] The UCONLY command is used to set upper case mode on and off. When UCONLY is on, all lower case letters encountered during a SEND will be converted to upper case. Received characters are not affected. Note that this command does not have any effect on normal terminal mode operation or on the files on your disk. ~End ~B VE VErsion The VERSION command gives you certain information about the versions of Crosstalk Mk.4, DOS, and XVI/4 in use. ~End ~B VI VIdeo [Mono | CGA | EGA | PGA] The VIDEO command allows you to optimize Crosstalk's performance for your particular type of display hardware. Setting Used for ------- -------- Mono Monochrome screens, either on mono adaptors or non-flickering color adapters. Useful for Compaq portables. CGA IBM Color Graphics Adapter, other flickering color boards. EGA IBM Enhanced Graphics Adapter, including the PS/2's VGA. PGA IBM Professional Graphics adapter. ~End ~B WA WAit [Echo | Quiet <integer> | Delay <integer> | Char <character> | ... For <character> | Prompt <integer> | Until <time> | Manual] The WAIT command tells Crosstalk to wait between lines when performing a script file. The options available with the WAIT command are: Condition Effect --------- ------ Echo Wait for a carriage return, then do the next line in the script file. Quiet X Wait until the line is "quiet" (i.e., no characters received) for X tenths of a second, then do the next line in the script file. Delay X Wait for a period of X tenths of a second, then do the next line. Char 'x' Wait until the character "x" is received from the communications line, then send the next line. For 'x' Same as "char 'x'", above. Prompt X Wait for X characters from the communications line, then do the next line in the file. Until HH:MM Wait until the time described by HH:MM, then do the next line in the file. Note that time must be expressed in 24 hour (military-style) format. Manual Suspend script processing until a "DO" command is issued. ~End ~B WR This command is not used in XVI/4. ~End ~B XD XDos The XDOS command tells Crosstalk to exit to DOS without hanging up the phone line. You may run any other program and return to Crosstalk, and your connection will still be intact. ~End ~B XK XK <filespec> The XKermit command transmits files to a remote system which is compatible with the KERMIT file transfer protocol. "Wildcard" file names are allowed. ~End ~B XM XMit <filespec> The XMIT command transmits files to another Crosstalk system using Crosstalk protocol. "Wildcard" file names are allowed. An optional target drive name may be given after the file name. Note that the XMIT command should only be used when calling into an answer-mode XVI/4, Crosstalk XVI, Crosstalk Mk.4, or Transporter system. The chart below shows some example XMIT commands: Command Action ------- ------ XMIT *.ASM Sends all the files with the type .ASM to the other system. XMIT BERT Send the file BERT from the default drive to the other system. XMIT B:FRED C: Send the file B:FRED to drive C: on the other system. ~End ~B XK XK <filespec> The XKermit command transmits files to a remote system which is compatible with the KERMIT file transfer protocol. "Wildcard" file names are allowed. ~End ~B XR XR <filespec> The XR command is used to send files to a Crosstalk Mk.4 host using DART protocol. To transfer a file or group of files to the distant system from yours, press the attention key and command "XR <filespec>". Commanding XR *.* on your system, while communicating with a Crosstalk Mk.4 host using the DART protocol, will upload all the files in the current directory on your system to the distant system. ~End ~B XT XType [Sum | Crc | K | G] The XType command tells CROSSTALK the mode of the XMODEM protocol to use when transferring files. Mode Description ---- ----------- SUM The original XMODEM protocol, with checksum error detection. CRC Normal XMODEM protocol, but uses a 16-bit CRC for error detection. K Uses 1K blocks with a 16-bit CRC for error detection. G Only for use with an error free connection. ~End ~B XX XXmodem <filename> The XXMODEM command is used to send files from your computer to another system using the XMODEM protocol. To send a file from your computer to another system running XMODEM, first tell the other system to prepare to receive a file, then press the ATTENTION key, and command: "XX <filename>". The type of XMODEM transfer used depends upon the setting of XType. You may override the XType setting with a command line option: XX <filename> /mode, where mode may be: SUM = original XMODEM protocol with checksum error detection CRC = normal XMODEM protocol with 16-bit CRC error detection K = large blocks (1K) sent with 16-bit CRC error detection G = Go mode, no error detection (assumes error-free link) For instance, to force CRC mode, use "XX <filename> /CRC". ~End ~B XZ XZ <filespec> The XZ command is used to send files to a host using ZMODEM protocol. To transfer a file or group of files to the distant system from yours, make sure the host is ready to receive the files, then press the attention key and command "XZ <filespec>". ~End ~B X4 X4 <valid Crosstalk Mk.4 command> The X4 (Crosstalk Mk.4 EXEC) command gives you access to all the power of Crosstalk Mk.4, from the XVI/4 command line, or from a script. This allows you to, for example, use the Crosstalk Mk.4 print spooler, which runs in another Crosstalk Mk.4 session and allows printing a file while you are online or performing another operation within the XVI/4. To run the print spooler from XVI/4, command X4 do pspool myfile the name "myfile" being replaced with the name of the file you want to print, of course. Please note that because this command uses Crosstalk Mk.4 directly to execute your commands, you will receive Crosstalk Mk.4 error messages and prompts, as necessary. ~End
