modemu2k v0.1.0555

modemu2k is a fork of modemu, originally developed by Toru Egashira

(Build status https://github.com/theimpossibleastronaut/modemu2k/actions/workflows/c-cpp.yml)

What is modemu2k?

modemu2k adds telnet capability to a comm program. It can redirect telnet I/O to a pty so that a comm program can handle the pty as a tty with a real modem, and allows you to use a comm program's scripting and file transfer features over telnet. Now supports IPv6 connections.

Issues and bug reporting

Dependencies

gettext (optional, for translations)
flex

Compilation

meson builddir
cd builddir

Use meson configure to see extra options

ninja

ninja install is optional. The binary can be run from the build directory; however, installation is required to use the translations, and to create and install a script (m2k-minicom) that can invoke minicom (see below).

Sample Usage

Note: while in the program if backspace doesn't work, use CTRL+H.

1) Stand alone usage

Invoked with no option,

  modemu2k

modemu2k reads from standard input and writes to standard output. Input

atd"localhost [port]

(prompt ">" is not shown) You will see your host's login prompt (if a server is running). When you disconnect, you will get "NO CARRIER" indication. Then input

at%q

to quit modemu2k.

2) With a comm program

(This example uses minicom as the comm program)

Invoke with "-c" option,

  modemu2k -e "AT%B0=1%B1=1&W" -c "minicom -l -tansi -con -p %s"

From within the comm program, if you have a server running, to connect you can enter:

  atd"localhost

You could also connect to a BBS. For some telnet addresses, see:

The Rusty Mailbox (telnet to trmb.ca, port 2030)
Synchronet BBS List

To quit modemu2k, just quit the comm program.

A script to invoke minicom as mentioned above will be installed to your bin directory when make install is run.

Escaping to command mode and returning

To escape to command mode, use '+++'. Use ATO to return to online mode.

Hanging up a call/closing a connection

If you are connected to a server where gracefully logging out isn't possible, to "hang up" or close the connection you can escape to command mode and enter 'ATH`.

Extra Notes

(*) Almost all file xfer protocols require 8bit through connection, which means Modemu2k must be in the binary transmission mode. See %B command description in the man page.
