Hello, I developed with C a simple communication program between my Palm and a PC application running as server. I use simple AT commands to call the PC's modem and to establish a communication channel. Then I use a protocol I invented to login and exchange data with the server.
Basically, this protocol is layered in subprotocols: a protocol to format packets of data with error check data ( a simple checksum ) is the lower protocol, while higher protocols exchange files and implement server autentication.
My question is: can I do the same thing ( point to point communication using modems ) by using an existent communication library? Does such a library exist? Can anyone give me a hint on a simple and robust communication library to use to implement a server waiting for a client call?
Thank you all for the help,
