picocom – minimal dumb-terminal emulation program

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. It can be used in embedded systems, since its memory footprint is rather small (approximately 40K, when stripped and minimally configured).

This is free and open source software.
