Description
This routines sends a command to the command line interpreter. The command will be executed once the new line character is received, so we recommend all command strings include a new line (i.e. "\n") as the final character. The buffer size, has been set to 1024 bytes, so all commands must be no greater than this length. There is no filtering of commands, so it is possible to crash or terminate the command line interpreter, for example; by sending "exit\n" or "echo off\n", as commands.
