42 Qodem is an open-source clone implementation of the popular DOS-based
43 Qmodem serial communications program. Qodem incorporates many features
44 that are useful on several kinds of text-based consoles such as scroll‐
45 back buffer, session capture, screen dump, dialing directory, and also
46 includes serial port handling and modem dialing.
47 The major features of Qodem are:
49 * Unicode display: translation of CP437 (PC VGA), VT100 DEC Special
51 Graphics characters, VT220 National Replacement Character sets,
52 etc., to Unicode
53 * Terminal interface conveniences: scrollback buffer, capture file,
55 screen dump, dialing directory, keyboard macros, script support
56 * Connection methods: serial, local shell, command line, telnet,
58 ssh, rlogin, raw socket
59 * Emulations: ANSI, Avatar, VT52, VT100/102, VT220, Linux, XTerm,
61 PETSCII (Commodore), and ATASCII (Atari).
62 * Transfer protocols: Xmodem, Ymodem, Zmodem, and Kermit

161
164 Qodem supports the following connection methods:
165 MODEM Calls the remote system by dialing a phone number.
168 LOCAL Spawns a local shell in a pseudo-tty.
170 RLOGIN Connects to the remote system using the rlogin protocol. Qodem
172 can either spawn an executable to connect (e.g. 'rlogin') or use
173 its own networking code. Its own networking code will only run
174 successfully if Qodem is running as root, due to the need to
175 bind to a privileged port. See the rlogin and use_exter‐
176 nal_rlogin options in qodemrc.
177 SSH Connects to the remote system using the ssh protocol. Qodem can
179 either spawn an executable to connect (e.g. 'ssh') or use its
180 own networking code. See the ssh and use_external_ssh options
181 in qodemrc.
182 TELNET Connects to the remote system using the telnet protocol. Qodem
184 can either spawn an executable to connect (e.g. 'telnet') or use
185 its own networking code. See the telnet and use_external_telnet
186 options in qodemrc.
187 SOCKET Connects to the remote system using a raw TCP socket.
189 CMDLINE
191 Spawns the command line in a pseudo-tty.
192
195 Emulations supported by Qodem and their status follows. Note that TTY,
196 DEBUG, ANSI.SYS, AVATAR, LINUX, and XTERM emulations can be set to
197 CP437 (DOS VGA), ISO-8859-1, CP720 (DOS Arabic), CP737 (DOS Greek),
198 CP775 (DOS Baltic Rim), CP850 (DOS West European), CP852 (DOS Central
199 European), CP857 (DOS Turkish), CP858 (DOS West European+Euro), CP860
200 (DOS Portuguese), CP862 (DOS Hebrew), CP863 (DOS Quebecois), CP866 (DOS
201 Cyrillic), Windows-1250 (Central/East European), Windows-1251 (Cyril‐
202 lic), Windows-1252 (West European), KOI8-R (Russian), and KOI8-U
203 (Ukrainian).
204 When 8-bit characters are used (see Alt-; Codepage below), the C0 con‐
206 trol characters (0x00 - 0x1F, 0x7F) are mapped to the equivalent CP437
207 glyphs when there are no glyphs defined in that range for the set code‐
208 page.
209 ANSI This is the DOS-based "ANSI.SYS" emulation plus a few more codes
212 than the original ANSI.SYS. It supports DSR 6 (Cursor Position)
213 which many BBSes used to "autodetect" ANSI, and the following
214 ANSI X3.64 functions: ICH, DCH, IL, DL, VPA, CHA, CHT, and REP.
215 It also supports "ANSI Music" sequences that follow the "PLAY"
216 command syntax; it plays these tones via SDL.
217 AVATAR This is the BBS-era Avatar ("Advanced Video Attribute Terminal
219 Assembler and Recreator") emulation. It supports all of the
220 "Extended AVT/0" commands as per George A. Stanislav's 1 May
221 1989 document except for transmitting PC keyboard scan codes.
222 It also includes ANSI fallback capability.
223 VT52 Fairly complete. Does not support HOLD SCREEN mode. Graphics
225 mode glyphs that do not have direct Unicode equivalents render
226 as a hatch.
227 VT100 Identical to VT102 except in how it responds to Device At‐
229 tributes function.
230 VT102 Fairly complete. Does not support smooth scrolling, printing,
232 keyboard locking, and hardware tests. Many numeric keypad char‐
233 acters also do not work correctly due to console NUM LOCK han‐
234 dling. 132-column output is only supported if the host console
235 / window is already 132 columns or wider; Qodem does not issue
236 resize commands to the host console for 80/132 column switching
237 codes.
238 VT220 Fairly complete. Converts National Replacement Character sets
240 and DEC Supplemental Graphics characters to Unicode. In addi‐
241 tion to limitations of VT102, also the following features are
242 not supported: user-defined keys (DECUDK), downloadable fonts
243 (DECDLD), VT100/ANSI compatibility mode (DECSCL).
244 TTY This emulation supports bare control character handling
246 (backspace, newline, etc.) and litte else. Characters that
247 would be overwritten with underscores are instead made under‐
248 lined as old teletypes would do.
249 DEBUG This emulation displays all incoming characters in a format sim‐
251 ilar to a hex dump.
252 LINUX This emulation has two modes: PC VGA (LINUX) and UTF-8 (L_UTF8).
254 This emulation is similar to VT102 but also recognizes the Linux
255 private mode sequences and ECMA-48 sequences VPA, CNL, CPL, ECH,
256 CHA, VPA, VPR, and HPA. In addition to VT102 limitations, also
257 the following features are not supported: selecting ISO 646/ISO
258 8859-1/UTF-8 character sets, X11 mouse reporting, and setting
259 the scroll/caps/numlock leds.
260 XTERM This emulation has two modes: PC VGA (XTERM) and UTF-8 (X_UTF8).
262 It recognizes everything in LINUX, VT220, and a few more XTerm
263 sequences. It does not support most of the advanced features
264 unique to XTerm such as Tektronix 4014 mode, alternate screen
265 buffer, and many more. It is intended to support XTerm applica‐
266 tions that only use the sequences in the 'xterm' terminfo entry.
267 PETSCII
269 This very loosely emulates a 40-column Commodore 64/128. Colors
270 are not quite right due to the IBM CGA colors being unable to
271 match the Commodore colors. Uppercase/lowercase affect new
272 characters rather than the whole screen. This emulation re‐
273 quires the C64 Pro Mono font from Style, available at
274 http://style64.org/c64-truetype/ . (Note that this font is only
275 licensed to software packages that are "freely provided to end
276 users". Entities wishing to ship packages that are not "freely
277 provided to end users" will need to either remove this font, or
278 negotiate a separate license agreement by contacting Style at
279 http://style64.org/contact-style .)
280 ATASCII
282 This emulates the 8-bit Atari 400/800 series.
283
286 Protocols supported by Qodem and their status follows:
287 XMODEM Supports original Xmodem, Xmodem-1k, Xmodem-CRC16, and Xmodem-G.
289 Also supports "Xmodem Relaxed", a variant of original Xmodem
290 with longer timeouts.
291 YMODEM Supports Ymodem and Ymodem-G. If a file exists, it will be ap‐
293 pended to.
294 ZMODEM Supports resume (crash recovery) and auto-start. Does not yet
296 support changing block size on errors, so transfers over unreli‐
297 able serial/modem connections might incur significant perfor‐
298 mance penalties.
299 KERMIT Supports the original robust (slow) Kermit plus streaming, slid‐
301 ing windows, and autostart. On reliable connections with
302 streaming it should perform reasonably well. Does not yet sup‐
303 port long or extra-long packets, RESEND/REGET, or server mode.
304
307 Phone Book
308 When Qodem first starts up, by default it will start in the phone book.
309 The menu on the bottom half of the screen lists the various actions
310 available. When editing a phone book entry, the status line will
311 change to show options for each field. Connecting to a system or leav‐
312 ing the phone book puts Qodem in Terminal Mode.
313 Terminal Mode
315 Terminal Mode is the main Qodem terminal emulator interface. Alt-Z
316 will bring up a help menu. While in Terminal Mode the following ac‐
317 tions are supported:
318 Alt-D Phone Book
320 This brings up the phone book.
321 Alt-G Term Emulation
323 This brings up a menu to select the terminal emulation. Select‐
324 ing the active terminal emulation will prompt to reset the emu‐
325 lation state; this may be useful to recover from corrupted es‐
326 cape sequences.
327 Alt-C Clear Screen
329 This clears the screen and homes the cursor.
330 Alt-F Execute Script
332 This prompts for a filename, and then executes that file as a
333 script. Any program that reads from standard input and writes
334 to standard output can be run as a script. See the section be‐
335 low on script support.
336 Alt-K Send BREAK
338 When connected via serial mode or modem, this calls tcsend‐
339 break() to send a true "Break Signal" on the serial line.
340 Alt-P Capture File
342 Enable/disable capture to file. Four capture formats are sup‐
343 ported: "raw", "normal", "html", and "ask". "Raw" format saves
344 every byte as received from the other side before emulation pro‐
345 cessing; "normal" saves UTF-8 characters after emulation pro‐
346 cessing; "html" saves in HTML format with Unicode entities and
347 color attributes after emulation processing; "ask" will bring up
348 a dialog to select which format to use every time capture is en‐
349 abled. ASCII file transfers will be included in the capture
350 file; other file transfers (Xmodem, Ymodem, Zmodem, Kermit) are
351 excluded from the capture file.
352 Alt-S Split Screen
354 This actives split screen mode, in which local characters are
355 accumulated in a buffer before sending to the remote side. To
356 send carriage return, enter "^M".
357 Alt-T Screen Dump
359 This prompts for a filename, and then saves the current view to
360 that file. Three screen dump formats are supported: "normal",
361 "html", and "ask". "normal" saves UTF-8 characters after emula‐
362 tion processing; "html" saves in HTML format with Unicode enti‐
363 ties and color attributes after emulation processing; "ask" will
364 bring up a dialog to select which format to use every time the
365 screen is dumped.
366 Alt-Y COM Parameters
368 This brings up a menu to alter the serial port settings.
369 PgUp Upload Files
371 This brings up the file upload menu. Note that CTRL-PgUp and
372 ALT-PgUp may also work depending on the terminfo for the host
373 terminal.
374 PgDn Download Files
376 This brings up the file download menu. Note that CTRL-PgDn and
377 ALT-PgDn may also work depending on the terminfo for the host
378 terminal.
379 Alt-\ Alt Code Key
381 This brings up a dialog to enter the 3-digit decimal value
382 (0-255) for an 8-bit byte or a 4-digit hexadecimal value
383 (0-ffff) for a 16-bit Unicode character (L_UTF8 and X_UTF8
384 only).
385 Alt-; Codepage
387 This brings up a dialog to change the current codepage. Code‐
388 pages are limited by the current emulation. VT52, VT100, VT102,
389 VT220, L_UTF8, X_UTF8, PETSCII, and ATASCII have their own code‐
390 page; LINUX, XTERM, ANSI, AVATAR, TTY, and DEBUG emulations can
391 be set to: CP437 (VGA), ISO-8859-1, CP720 (Arabic), CP737
392 (Greek), CP775 (Baltic Rim), CP850 (Western European), CP852
393 (Central European), CP857 (Turkish), CP858 (Western European
394 with euro), CP860 (Portuguese), CP862 (Hebrew), CP863 (Quebec
395 French), CP866 (Cyrillic), CP1250 (Central/Eastern European),
396 CP1251 (Cyrillic), CP1252 (Western European), KOI8_R (Rus‐
397 sian),and KOI8_U (Ukrainian).
398 Alt-/ Scroll Back
400 This selects the scrollback buffer. When viewing the buffer,
401 "S" saves to file and "C" clears the scrollback buffer. By de‐
402 fault Qodem supports up to 20000 lines of scrollback; this can
403 be changed by editing scrollback_max in scrollback.c. Three
404 scrollback save formats are supported: "normal", "html", and
405 "ask". "normal" saves UTF-8 characters after emulation process‐
406 ing; "html" saves in HTML format with Unicode entities and color
407 attributes after emulation processing; "ask" will bring up a di‐
408 alog to select which format to use every time the scrollback is
409 saved.
410 Alt-H Hangup/Close
412 This hangs up the modem (drops DTR) or closes the remote connec‐
413 tion (kills the child process).
414 Alt-L Log View
416 This brings the session log up in an editor. The session log
417 stores information about connect, disconnect, and file up‐
418 load/download events.
419 Alt-M Mail Reader
421 This spawns the mail reader, by default mm.
422 Alt-X Exit Qodem
424 This prompts to exit Qodem. When not connected, Ctrl-C will
425 also bring up the exit prompt.
426 Alt-A Translate Tables
428 This brings up the translate tables editor. Both incoming and
429 outgoing bytes can be changed or stripped (set to ASCII NUL
430 (0)). Note that 8-bit INPUT translation occurs before both emu‐
431 lation processing and UTF-8 decoding. Unicode INPUT translation
432 occurs before code points are written to the scrollback buffer;
433 Unicode OUTPUT translation occurs after code points are read
434 from the keyboard.
435 Alt-J Function Keys
437 This brings up the keyboard macro editor. Keyboard macros sup‐
438 port substitutions for control characters including carriage re‐
439 turn ("^M"), the phone book entry username ("$USERNAME"), and
440 the phone book entry password ("$PASSWORD").
441 Alt-N Configuration
443 This brings the qodemrc options file up in an editor.
444 Alt-: Colors
446 This brings the colors.cfg colors file up in an editor.
447 Alt-O Modem Config
449 This brings up the modem configuration dialog.
450 Alt-R OS Shell
452 This spawns a system shell.
453 Alt-V View File
455 This brings up a prompt to view a file in an editor.
456 Alt-W List Directory
458 This brings up a directory listing.
459 Alt-0 Session Log
461 This toggles the session log on or off.
462 Alt-1 XON/XOFF Flow Ctrl
464 When connected via modem or serial port, this toggles XON/XOFF
465 on or off.
466 Alt-2 Backspace/Del Mode
468 This selects whether the backspace key on the keyboard sends an
469 ASCII backspace (^H) or an ASCII DEL (127) character. Alt-\ 0 0
470 8 can always be used to send true backspace; Alt-\ 1 2 7 can be
471 used to send true DEL. Note that VT220 emulation always sends
472 DEL when the backspace key is pressed.
473 Alt-3 Line Wrap
475 This toggles line wrap mode on or off. When line wrap mode is
476 enabled, if a character is received when the cursor is at the
477 right margin it will wrap to the first column of the next line.
478 Alt-4 Display NULL
480 This selects whether ASCII NUL (0) will be displayed as a
481 blank/space or stripped.
482 Alt-5 Host Mode
484 This switches Qodem into Host Mode.
485 Alt-6 Batch Entry Window
487 This brings up the list of upload files used by Ymodem, Zmodem,
488 and Kermit uploads.
489 Alt-7 Status Line Info
491 This selects between two formats for the status line.
492 Alt-8 Hi-Bit Strip
494 This selects whether or not to clear the 8th bit of all incoming
495 bytes. Note that high-bit stripping occurs before both emula‐
496 tion processing and UTF-8 decoding.
497 Alt-9 Serial Port
499 This opens or closes the serial port. If already connected to a
500 non-serial/modem remote host, this does nothing.
501 Alt-B Beeps & Bells
503 This toggles beep support on or off. When beep support is on,
504 beeps from the remote host will be played by Qodem. In LINUX
505 emulation, Qodem supports setting the tone and duration of the
506 beep as specified in console-codes(4).
507 Alt-E Half/Full Duplex
509 This toggles between half and full duplex.
510 Alt-I Qodem Information
512 This displays the Qodem splash screen which includes the version
513 and build date.
514 Alt-U Scrollback Record
516 This selects whether or not lines that scroll off the top of the
517 screen will be saved to the scrollback buffer.
518 Alt-= Doorway Mode
520 This selects between three doorway modes: "Doorway OFF", "Door‐
521 way MIXED" and "Doorway FULL". When doorway mode is "Doorway
522 OFF", terminal mode responds to all of its command keys as de‐
523 scribed in this section. When doorway mode is "Doorway FULL",
524 all Alt- command keystrokes except Alt-= are passed to the re‐
525 mote side. When doorway mode is "Doorway MIXED", terminal mode
526 supports a few commands but passes the majority of Alt- command
527 keystrokes to the remote side. The default commands supported
528 in "Doorway MIXED" mode are:
529 Alt-D Phone Book
530 Alt-P Capture
531 Alt-T Screen Dump
532 Alt-Y COM Parameters
533 Alt-Z Menu
534 Alt-/ Scrollback
535 Alt-PgUp or Ctrl-PgUp Upload Files
536 Alt-PgDn or Ctrl-PgDn Download Files
537 Alt-- Status Lines
539 This toggles the status line on or off.
540 Alt-+ CR/CRLF Mode
542 This toggles whether or not received carriage returns imply line
543 feed or not.
544 Alt-, ANSI Music
546 This toggles ANSI music support on or off.
547
550 Qodem supports Unicode (UTF-8 encoding only) in the following functions
551 only: keyboard macros; phone book entries (NAME, USERNAME, and PASS‐
552 WORD); modem device name.
553 UTF-8 is NOT supported in filenames, modem strings, and remote ad‐
555 dresses.
556
559 Qodem does not have its own scripting language. Instead, any program
560 that reads and writes to the standard input and output can be run as a
561 Qodem script:
562 * Characters sent from the remote connection are visible to the
564 script in its standard input.
565 * Characters the script emits to its standard output are passed on
567 the remote connection.
568 * Messages to the standard error are reported to the user and also
570 recorded in the session log.
571 Since scripts are communicating with the remote system and not Qodem
573 itself, they are unable to script Qodem's behavior, e.g. change the
574 terminal emulation, hangup and dial another phone book entry, download
575 a file, etc. However, they can be written in any language, and they
576 can be tested outside Qodem.
577 Scripts replace the user, and as such have similar constraints:
579 * Script standard input, output, and error must all be in UTF-8 en‐
581 coding.
582 * Scripts should send carriage return (0x0D, or \r) instead of new
584 line (0x0A, or \n) to the remote side - the same as if a user
585 pressed the Enter key. They should expect to see either bare
586 carriage return (0x0D, or \r) or carriage return followed by
587 newline (0x0D 0x0A, or \r\n) from the remote side.
588 * Input and output translate byte translation (the Alt-A Translate
590 Tables) are honored for scripts.
591 * While a script is running:
593 - Zmodem and Kermit autostart are disabled.
594 - Keyboard function key macros are disabled.
595 - Qodem functions accessed through the Alt-character
596 combinations and PgUp/PgDn are unavailable.
597 - Pressing Alt-P will pause the script.
598 * While a script is paused:
600 - The script will receive nothing on its standard input.
601 - Anything in the script's standard output will be held until
602 the script is resumed.
603 - The script process will not be signaled; it may continue
604 running in its own process.
605 - The only Alt-character function recognized is AltP to
606 resume the script. All other Alt- keys will be ignored.
607 - Keys pressed will be sent directly to the remote system.
608 - Keyboard function key macros will work.
609 Scripts are launched in two ways:
611 * In TERMINAL mode, press Alt-F and enter the script filename. The
613 script will start immediately.
614 * In the phone book, add a script filename to a phone book entry.
616 The script will start once that entry is connected.
617 Script command-line arguments can be passed directly in both the Alt-F
619 script dialog and the phone book linked script field. For example,
620 pressing Alt-F and entering "my_script.pl arg1" will launch
621 my_script.pl and with its first command-line argument ($ARGV[0] in

626 Qodem makes use of the following variables:
627 HOME The user's home directory. Qodem creates two directories:
629 $HOME/.qodem for qodem's internal files (phone book, keyboard
630 macro files, translate tables, etc.) and $HOME/qodem for up‐
631 loaded and downloaded files, session log, capture, etc.
632 EDITOR If present, this will be used when spawning external editors
634 (log view, edit configuration, view file, edit phone book note).
635 If not present, by default (editable in the options file) use
636 vi.
637 ESCDELAY

640 get_wch() and wget_wch() functions to determine if a user
641 pressed bare ESCAPE. On some systems pressing ESCAPE may re‐
642 quire up to a full second before Qodem can process it. For Qo‐
