Subject: Re: Two-way serial comms with no internal mods...

I did'nt know about the line-in pin capable of transmitting or receiving?
Are you sure? I think it has to be modded to have full duplex.
Half duplex is possible with no mod.
Hoewever, it still need an electrical interface for rs232.

What kind of communication do you want? remote control?
