• picocom - minimal dumb-terminal emulation program - LinuxLinks

  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).
