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 set 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. Shift-PrtSc Standard DOS Print-screen, dump screen image to printer. unassigned HOLDSCRN DEC style Holdscreen, same as typing Control-S. "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. CONNECT ESCAPE COMMANDS: Type the Kermit escape character (normally "^σ"), 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.

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. When National Replacement Characters are selected from the DEC keyboard Setup menu and are activated by CSI ? 42 h outgoing keystrokes are mapped as well as incoming characters; the emulator acts on only incoming chars. Real VT300 terminals operate with 80x24 or 132x24 screen dimensions; the emulator supports whatever dimensions the user has constructed outside of MS Kermit. 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 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.σ 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.
