ARRGGHHHH....had to get it out.

I am going insaine here; - i have my little boardcomputer, and i have a Falcom GSM modem that i have connected to the serial port.

I am to develop a protocol that i can use between this PC and a host somewhere, that are to deliver data through this GSM device.

Anyone with an idea of a good protocol to use - or some hints, as i understand it i cannot develop a simple ack->nak thing, since the GSM isnt very reliable.

I have surfed the net to end....!!

Please have in mind we are talking about 8052 - i have no intention implementing WAP, TCP/IP or something here.....going to code every byte action myself....

Hope you can help, thanks for your time.
