Enter Modem Debug Mode
modem.debug(ip, portd, [portc])
Enter debug pass-through mode.
If only portd is provided, then the [ESC] key will toggle between data and control modes (where power, reset, and DTR can be controlled).
If both portd and portc are opened, then separate sockets are used.
Positive numbers for portd and portc represent a client operation.
Negative numbers for portd and portc represent a server listen.
e.g.
modem.debug('192.168.0.117', 9001, 9002) -> will connect to a PC on ports 9001 and 9002.
e.g.
modem.debug('', -9001) -> will listen for a connection on port 9001, and allow any IP address.
The ip.buffer will listen for a maximum of 10 minutes before aborting the debug server. Once a socket is connected, it can remain connected.
Once the socket closes, the debug process is stopped (you have to reinitiate it).
