microcom

microcom is a minimalistic terminal program for communicating with devices over a serial connection (e.g. embedded systems, switches, modems). It features connection via RS232 serial interfaces (including setting of transfer rates) as well as in "Telnet mode" as specified in RFC 2217.

Installation

microcom depends on the readline library.

If you just cloned this repository, you also need to install autoconf, automake, and the autoconf archive first. Then change to the project's root directy and do:

autoreconf -i

If you extracted microcom from a release tarball, this previous step should not be needed.

Now continue with building and installing microcom:

./configure
make
sudo make install

By default, microcom is installed into /usr/local/bin/. Use ./configure --prefix=YOURPATH to change that, and see ./configure --help for more options related to building and installation.

Usage

The typical usage with TTY devices looks like this:

microcom --speed=115200 --port=/dev/ttyS0

To connect to remote serial ports via RFC 2217, use the --telnet option instead:

microcom --speed=115200 --telnet=somehost:port

For the full list of options, see microcom --help.

During the connection, you can get to the microcom menu by pressing Ctrl-\. Various options are available there, like setting flow control, RTS and DTR. See help for a full list.
