File MSVIBM.VT 9 June 1993 MS-DOS KERMIT 3.13 TERMINAL EMULATOR TECHNICAL SUMMARY Most recent update: Tue Jun 15 17:04:57 1993 This file describes the text terminal emulator in the IBM PC version of MS-DOS Kermit. See the file MSVIBM.TEK for details about the Tektronix graphics emulator. This file is in three main sections: 1. The VT320/VT102/VT52/Heath-19 Emulator 2. The DG DASHER D463 and D470 Emulator 3. Compose-Key Sequences 1.

Command SET TERMINAL CONTROL {8-BIT | 7-BIT}, and an equivalent command from the host, determines the usage for output text; use of parity forces 7-bit mode. CSI is decimal 155, SS3 is decimal 143. Similarly, DCS is decimal 144 or ESC P and ST is decimal 156 or ESC \. APC is decimal 159 or ESC _. --------------------------------------------------------------------------- Codes sent by DEC and Heath arrow keys Key Verb IBM VT320/VT102 mode VT52/H19 mode key Cursor Application Cursor or Application up uparr up CSI A SS3 A ESC A down dnarr down CSI B SS3 B ESC B right rtarr right CSI C SS3 C ESC C left lfarr left CSI D SS3 D ESC D Codes sent by DEC editing keys, not preassigned to keys.

See below for method. An often confusing item is knowing the mode of the auxillary keypad: numeric or application. Digital Equipment Corporation designed the terminal to change modes only under command from the remote computer and not at all from the keyboard. So the startup state is numeric/cursor mode, and reception of escape sequences "ESC [ ? 1 h" or "l" changes the mode. Kermit verbs for the keypad and cursor keys generate the correct escape sequences appropriate to the current mode and terminal type. A best attempt is made to safely test for the 101/102 key Enhanced keyboard and use it if present. If it is present then the keyboard translator separates the individual arrow keys from those on the numeric keypad and also separates the asterisk and forward slash keys on the keypad from those on the regular typewriter keyboard. These special Enhanced keyboard keys are reported as scan codes with 4096 added to the base scan code. OTHER IBM KEYS OPERATIONAL IN CONNECT MODE: IBM key IBM Verb Action Keypad Del Send ASCII Del code (rubout) \127 Backspace (<-) Send ASCII Del code (rubout) \127 (BS is \8) Keypad - MODELINE Toggle mode line on/off (only if Mode Line is enabled and not used by the host). Alt - TERMTYPE Toggle between text and Tek terminal types. Alt = RESET Clear screen and reset terminal emulator to starting (setup) state. Alt b BREAK Send a BREAK signal Alt h HELP Show drop down help menu (detailed below) Alt s STATUS Show settings Alt x EXIT Exit Connect mode, back to Kermit prompt Alt n Home HOMSCN Roll screen up (text down) to beginning of storage. End ENDSCN Roll screen down (text up) to end of storage. PgUp UPSCN Roll screen up (back, earlier) one screen. PgDn DNSCN Roll screen down (forward, later) one screen. Ctrl-PgUp UPONE Roll screen up one line. Ctrl-PdDn DNONE Roll screen down one line. Control-PrtSc PRTSCN Toggle on/off copying of received text to printer, "PRN" shows on far right of mode line when activated. Control-End DUMP Dump image of screen to a disk file or device. Default filename is KERMIT.SCN in the current directory. Use command SET DUMP to change the filename. Screen images are appended to the file, separated by formfeeds. Graphics screens go to files TEKPLT<digit digit>.TIF. Shift-PrtSc Standard DOS Print-screen, dump screen image to printer. unassigned HOLDSCRN DEC style Holdscreen, same as typing Control-S. ALT-N NEXTSESSION Change to next terminal session, only if using Kermit's internal TCP/IP protocol stack. unassigned NETHOLD Place Network connections "on hold". This means interrupt the normal PC to host connection and invoke the external network control program interface for session management. Works with 3Com(BAPI), Novell(NASI), UB-Net1, etc, but not with Kermit's internal TCP/IP protocol stack. unassigned RTONE scroll screen right one column unassigned RTPAGE scroll screen right by 20 columns unassigned LFONE scroll screen left by one column unassigned LFPAGE scroll screen left by 20 columns "Alt -" means hold down Alt and type minus on the upper key rank. This switches among the various kinds of emulation but does not change most operating parameters of the emulator. Follow a new selection with ALT = (verb RESET) to reset the emulator to the current type. CONNECT ESCAPE COMMANDS: Type the Kermit escape character (normally "^]"), then one of the keys below: (equivalent \Kverb) ? display this short list. HELP 0 send a null character. NULL A send Telnet "Are You There" sequence B send a BREAK signal. BREAK C close connect session & return to Kermit prompt. EXIT F dump screen to filespec, default is KERMIT.SCN. DUMP H hangup the phone or network connection HANGUP I send Telnet "Interrupt Process" sequence L send a Long BREAK signal LBREAK M toggle mode line on/off. MODELINE P push to DOS. DOS Q quit (suspend) logging. LOGOFF R resume logging. LOGON S show status. STATUS Kermit escape character itself: send it to the host. RESPONSES TO CHARACTERS RECEIVED BY THE VT/HEATH TERMINAL EMULATOR Spaces shown between characters of escape sequences are there for ease of reading. The actual sequences contain no spaces. Unknown escape sequences are absorbed and ignored. DEC VT320 and VT102 functions while in ANSI (non-VT52) mode, unsupported features are marked by an asterisk (*): Control Codes in C0 (no high bit) Area: Name ASCII value chart hex keyboard operation NUL 0/0 00h ^@ Ignored except during transparent printing ENQ 0/5 05h ^E Answerback message (response: "MS-DOS KERMIT") BEL 0/7 07h ^G Sound DEC style beep BS 0/8 08h ^H Backspace, move cursor left one character HT 0/9 09h ^I Horizontal tab, move cursor to next tabstop LF 0/10 0ah ^J Linefeed, move cursor down one line VT 0/11 0bh ^K Vertical Tab, treated as a line feed FF 0/12 0ch ^L Formfeed, treated as a line feed CR 0/13 0dh ^M Carriage return, move cursor to col 1 SO/LS1 0/14 0eh ^N Map character set in G1 to GL, locking shift SI/LS0 0/15 0fh ^O Map character set in G0 to GL, locking shift DC1 1/1 11h ^Q XON flow control, resume communication DC3 1/3 13h ^S XOFF flow control, suspend communication CAN 1/8 18h ^X Cancel escape & control sequence in progress SUB 1/10 1ah ^Z Treated as a CAN ESC 1/11 1bh ^[ Escape, start escape seq, cancel any others DEL 7/15 7fh ^_ ignored except during transparent printing All others are ignored. Control Codes in C1 (high bit set) Area: These are represented by ESC <code - 40h> in a 7-bit environment. When Controls is set to 7-bit output the emulator emits the 7-bit version but still responds to reception of both 7- and 8-bit versions. Only the VT220/320 emulator responds to these 8-bit codes; other text terminal types receive the byte without the high bit and the result may be unexpected. Please note that Kermit commands SET TERMINAL DISPLAY 8-bit or SET DISPLAY 8-bit are required to pass 8-bit codes to the VT320 terminal emulator; otherwise the high bit is removed with usually disconcerting results. VMS presumes an 8-bit channel with VT300's.

Terminated by ST. All others are ignored lease note the actions resulting from reception of OSC, PM, APC (and some CS commands): nothing shows on the screen until either: a) an ST arrives or b) another control sequence begins or c) the terminal emulator is reset (ALT =, keyboard verb RESET) Line noise can occassionally generate these characters.

VT420 Hebrew terminals add choices of Hebrew-ISO and Hebrew-7. MS-DOS Kermit has DEC Supplemental Graphics as the startup UPSS character set. If the size of the character set does not match the <ident> nothing happens. Startup defaults are ASCII in G0 and G1, ISO Latin-1 in G2 and G3, GL points to G0, GR points to G2. Activating DEC National Replacement Characters maps the NRC set selected by SET TERMINAL CHARACTER-SET <country> into G0..G3. Single and Locking shifts, SS2, SS3, LS0 (SI), LS1 (SO), LS1R, LS2, LS2R, LS3, LS3R determine which set is mapped to the GLeft or GRight area.

Double wide and/or double high characters are supported as space fillers and/or a repeated line. The DEC Technical character set occurs on VT340's but not on real VT320's. Real VT320 terminals operate with 80x24 or 132x24 screen dimensions; the emulator supports whatever dimensions the user has constructed outside of MS Kermit. However, the logical screen width will be set to 80 or 132 columns to match DEC terminals. Also real VT300's have no screen rollback nor horizontal scrolling capability.

[Note: there are several variations of DEC VT10x; the emulator comes closest to the VT102 as rendered in the DEC Rainbow computer. A real VT320 in VT100 mode removes access to G2 and G3; the VT102 has G2 and G3 holding ASCII.] VT52 is used as a submode of a VT320 (default) or a VT102. Only GL = G0 with ASCII is available. ESC F loads line drawing graphics, ESC G reloads ASCII. Heath-19. Same as for VT52 in non-ANSI mode, but while in ANSI mode ESC [ 10 m and ESC [ 11 m duplicate the ESC F and ESC G operations. 2. DATA GENERAL DASHER D463 AND D470 TERMINALS, NATIVE MODE Items marked with a * are not implemented in MS-DOS Kermit. XON/XOFF flow control should be set to outgoing only or none because these codes are also used as D463/D470 commands. Special D463/D470 Kermit command: SET TERMINAL COMPRESSED-TEXT {GRAPHICS, TEXT-132} The default is GRAPHICS, meaning compressed font characters are drawn as 5x14 dot pattern cells in IBM PC graphics mode, simulating a text screen. The compressed font used in Graphics mode is Code Page CP437 or CP850. Alternatively, TEXT-132 means switch to 132 column EGA/VGA text mode and show all text with that font. Graphics is considerably slower than Text and only 128 character cells are available across the screen (640 dots / 128 yields 5 dots per character cell including a separation dot). If Text is commanded and the display adapter cannot be switched to 132 column mode then Graphics is implemented by default. Compressed fonts are available only on EGA/VGA adapters and above, not on Monochrome, CGA, or Hercules. Note on line drawing, RS L and the RS G series of commands. The drawing remains intact so long as the graphics screen is viewed. It is not preserved if the user returns to the Kermit prompt or switches to the text screen (the ALT - hot key, keyboard verb \ktermtype). The reason is the basic screen is first drawn from the text screen and then line drawing dots are superimposed. Leaving this screen means the text screen could change and thus a fresh version of it will always overwrite the existing material. It is not possible to preserve the line drawings separately from the underlying simulated text screen. The Data General CEO_DRAW program provides a REFRESH command to restore graphics images. A Data General D463 terminal is a monochrome high resolution text and graphics terminal, a D470 is a similar full color terminal. The D470 has fewer screen dots than the D463 and uses a smaller graphics crosshair. A D463 graphics screen is 800 dots across by 576 high, a D470 graphic screen is 640 across by 480 high with 16 colors. Aside from a few status reports and the graphics details both terminals use the same core emulator. ANSI mode is not supported on either terminal; please use Kermit's VT320 instead. When the display adapter is in graphics mode character fonts are sought from the display adapter and, when Code Pages are active, from the DOS Code Page file EGA.SYS. Normal width characters can be drawn from that file, but compressed characters will be shown from a CP850 font if the current Code Page is other than CP437. The DOS file EGA.SYS must be in the current directory on along the PATH. CGA, monochrome, and Hercules video display adapters cannot use Code Pages; only EGA/VGA and above can. A D463 terminal is a 7-bit device and Kermit removes the high bit of a byte before passing it to the emulator. A D470, however, can use the high bit and the Kermit command SET DISPLAY {7, 8} is effective for its emulation.

Mouse support: While in graphics mode a Microsoft-compatible mouse may be used to control the graphics crosshair. The left mouse button sends the POINT command, and the right button sends the dgF1 keyboard verb. The DG F1 key frequently means "execute" to many utilities. On Data General keyboards POINT is the key combination CMD CURSOR-TYPE. Compound keys: See section at the end of this document.

Report is RS o , <crosshair> 0 <crosssize> <tracked> where <crosshair> is 0 or 1 for off/on, <crosssize> is 1 for D463 and 0 for D470, <tracked> is 0, 2, 4 or 6 for tracked devices of none, keyboard, mouse, both, respectively. RS G A Graphics cursor reset (no cursor, no tracking) RS G B Graphics cursor on RS G C Graphics cursor off RS G H <n> Graphics cursor track <n> bit field, 0 for nothing 2 for keyboard arrow keys, 4 for mouse, default nothing RS G I <n> *D470, set graphics crosshair (cursor) color. Not implemented because Kermit uses XOR with existing screen dots. RS G : <loc><null> Polygon fill (non-intersecting polygon) <loc> is up to 255 x,y pairs of sequential vertices, in location argument format.

Window text moves up one line, blank line is inserted at bottom. Cursor remains fixed on screen unless it is on a protected character, then a cursor right is executed. RS I Scroll down (in window). Window text moves down one line, blank line is inserted at top, cursor remains fixed on the screen. RS J Insert character. Insert a space at the curror, push right, lose excess. First protected character is temporary right margin. RS K Delete character at cursor position, pull left. First protected character is temporary right margin. RS L <loc_list><null> Line drawing.

COMPOSE-KEY SEQUENCES Compose-key sequences are available for entering special characters during all types of terminal emulation, as long as Kermit's TERMINAL CHARACTER-SET is LATIN1, or (for DG terminal emulation) DG-INTERNATIONAL, or (for DEC terminal emulation) DEC-MCS. Keyboard verb \Kcompose or \KdgSPCL (synonyms) must be assigned to a key. Press this key and then two more as illustrated in the following table Hexadecimal output codes are shown below for each case; "n/a" means no output is produced.
