JonFreeman 0:77803b3ee157 2 Command Line Interpreter code module.
JonFreeman 0:77803b3ee157 3 Purpose -
JonFreeman 0:77803b3ee157 4 Provides easy interface to pc terminal programme for use during programme development, debug etc.
JonFreeman 0:77803b3ee157 5 Also usable as comms subsystem in finished code for accepting commands, reporting data etc.
