picocom 1.7-1 (arm64 binary) in ubuntu trusty

 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.
