picocom - 3.1-2+b1 main

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.
