Description:

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 "terminal-window" to allow operator intervention
in PPP connection scripts (something like the MS Windows "open
terminal window before / after dialing" feature). It could also prove
useful in many other similar tasks. It is ideal for embedded systems
since its memory footprint is minimal (less than 20K, when stripped).
Apart from being a handy little tool, picocom source distribution
includes a simple, easy to use, and thoroughly documented
terminal-management library, which could serve other projects as well.
This library hides the termios(3) calls, and provides a less complex
and safer (though certainly less feature-rich) interface.
