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 \. --------------------------------------------------------------------------- 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 cur- rent 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 among H-19, VT52, VT100, VT320 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 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. 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), and UB-Net1. "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 operat- ing 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 IBM Verb) ? display this short list. HELP 0 send a null character. NULL 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 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. 1.17.3. Responses To Characters Received By the Terminal Emulator Spaces shown between characters of escape sequences are there for ease of read- ing. 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 (not supported) 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. Answerback is removed because it is a security risk. 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 VT320 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 VAXen presume an 8-bit channel with VT300's. Control codes in C1 (high bit set) area.

MS 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.

Response none Request DCS Pc; Pl | Ky1/St1...Kyn/Stn ST set User Definable Keys Pc = 0 clear all UDK definitions before starting, = 1 clear one key. Pl = 0 lock the keys, = 1 do not lock; MS Kermit never locks keys. Kyn/Stn are key identifier and definition string. Form of Kyn is two ascii digits, 17-34, representing the DEC key number for DEC F6 through DEC F20; F6 = 17, etc as per keyboard table well above. Stn is definition text written as a pair of hex characters per final definition byte; upper or lower case A..F are the same. Example: DCS 1; Pl | 28/48656c70 ST defines DEC key Help (verb decHelp) as the four characters "Help" and does not erase all UDK definitions. The lock indicator, Pl, is ignored by MS Kermit. 60 hex chars max.

Doing so does not invoke VT320 display area characteristics found with the formal VT320 method of CSI Ps $ }. Selective erasure character attribute is not supported. Sixel, soft characters, are not supported in text mode. Full system report and download, CSI 1 $ u and DCS 1 $ string ST, are not supported. User Definable Keys are not lockable. The keyboard is not lockable. Smooth scrolling is not supported. Double wide and/or double high characters are supported as space fillers and/or a repeated line. User Preferred Supplementary (character) Set, UPSS, is not selectable in the MS Kermit Set Term setup command repertory. Since the character sets under UPSS are ISO Latin-1 (96) and DEC Special Graphics (94) the host must first find which set is present so that it can be designated with the proper set size attribute. The host can also specify which set is under UPSS. All told, the user level Setup is not needed. 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 capability. Character sets: VT320 Character set storage areas G0 G1, G2, and G3 ------------------------------- -------------------------------- Any 94 char set Any 94 or 96 char set ASCII ("B"/94) default G1 default is ASCII ("B"/94), G2 and G3 defaults are ISO Latin-1 ("A"/96) Special Graphics ("0"/94, "2"/94) Alt-Rom ("1"/94) (MS-DOS Kermit only) Supplementary Graphics ("%5"/94) Technical (">"/94) (from VT340) User Preferred, UPSS, if Suppl Gr. UPSS if ISO Latin-1 or Suppl Gr. National Replacement Characters are forced into all sets when activated by CSI ? 42 h but only if a <country> has been previously selected by SET TERMINAL CHARACTER-SET <country> VT102 Character set storage areas G0 and G1 G2 and G3 -------------------------------- ---------------------------------- ASCII ("B"/94) Default ASCII ("B"/94) Default Special Graphics ("0"/94, "2"/94) Alt-Rom ("1"/94) (MS Kermit only) Supplementary Graphics ("%5"/94) Technical (">"/94) (from VT340) National Replacement Characters Always ASCII ("B"/94) are selected and activated by SET TERMINAL CHARACTER-SET <country> and affect only G0 and G1. [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 sub mode 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.
