The comms/picocom port
picocom-3.1 – minimal dumb-terminal emulation program
As its name suggests, picocom is a minimal dumb-terminal emulation
program. It is, in principle, very much like minicom, only it's pico
instead of mini!
It was designed to serve as a simple, manual, modem configuration,
testing, and debugging tool. It has also served (quite well) as a
low-tech serial communications program to allow access to all types of
devices that provide serial consoles. It could also prove useful in
many other similar tasks.
