Qodem is an open-source re-implementation of the once-popular Qmodem(tm) shareware communications package. Qodem (pronounced 'kodem', rhymes with 'modem') is now in beta. Its main features are:

• Terminal interface: scrollback buffer, capture file, screen dump
• Convenience: dialing directory, command-line invocation
• Connection methods: serial, local shell, telnet, ssh, rlogin, rsh
• Emulations: ANSI (with "ANSI music"), Avatar, VT52, VT100/102, VT220, Linux
• Transfer protocols: X/Y/Zmodem, Kermit
• Programmability: keyboard macros, full scripting

The latest (beta) version is 0.1.2. This version includes all of the features listed above except scripting and Kermit. Most users will want to download the non-localized English-only version (qodem-0.1.2_en.tar.gz) as it won't require setting the LANG environment variable to work.

Qodem seeks to fill a niche that the Internet era has left woefully vacant. Though all of the features listed above are present in many other programs (such as X11 terminals, MUDs, and IRC clients) none of them are easy to access on a mouse-less console. Qodem will allow the user to create a list of the host machines they access frequently along with their username and password, and -- regardless of the connection method required -- provide the same status bar and macros.

Please note that Qodem is NOT Qmodem(tm). Qmodem(tm) is a trademarked commercial program, last released by Mustang Software, Inc., a quality program that can handle all kinds of serial communications needs. Newer versions of QmodemPro(tm) for Windows (above 2.0) can connect to hosts via telnet. Qodem has many important behavior deviations from Qmodem(tm), please see the README file for greater details.

Why a Console-based Terminal Emulator?

"Why not?" :-)

More seriously, Qodem has several advantages over the native console or the typical (except for Xterm) "local shell" X-based emulator.

• Qodem strives to understand the emulation of its supported terminals as well as possible within the text character-cell metaphor, so Qodem can understand and respond to remote applications that the local console/emulator might not handle. For instance, Qodem can pass 'vttest's VT52 sub-mode test, whereas the raw Linux 2.4.24 console cannot. Qodem also understands Avatar, ANSI.SYS, and can even play "ANSI Music" on the raw Linux console.
• Qodem provides a lot of X-based emulator-isms to the text console: scrollback, screen dump, capture, etc. These functions are very handy when you work professionally at the console.
• Qodem provides access to X/Y/Zmodem upload and download protocols over almost any interactive network link (via local shell if nothing else). This is extremely useful for quick-and-dirty file transfers when firewalls are blocking the standard protocols.
• Qodem hopes to bundle all of this function inside a pleasant environment with some eye appeal. On the raw i386-based Linux console, Qodem uses PC-VGA glyphs to duplicate almost exactly the look and feel of the original Qmodem(tm). On any other console/emulator, Qodem maps received characters to PC VGA and then remaps them back out to the ncurses drawing characters. It's a subtle effect but usually works out well visually: regardless of console or emulator used you still see the lines, boxes and windows-with-corners you expect from modern console-based applications.

HS/Link

The Qodem Project is planning to port the public release code of the HS/Link bi-directional file transfer protocol to POSIX environments. No timetable is set, but the files themselves are available here. We are working under the assumption that the original author did in fact release the code as "public domain" with his statement here (originally here).
