Description:
minimal dumb-terminal emulation program
picocom 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.
