rcom is a small tool which captures serial dumps. Compiled and tested under unix.

For capturing my null modem serial I use:

rcom -l -s 115200 /dev/ttyS0

Typing ‘rcom’ without arguments will print the options.

Since version 1.2 you can use ‘tip’-like syntax as:

rcom ttya115200

Download here. Since 2016, there’s a git repository.

This software was almost entirely written by Olivier Piras and is the first and only project he (almost) completed!
