I need to connect 2 uC's and both are connected via RS232 to an Enfora Spider SA-G modem. The uC's don't have any PPP stack. I just need to send plain ASCII information from on uC to another. Can this be done? I have already done it with SMS, but we would like to change to GPRS.
Another problem is that the IP are asigned dynamicaly. If it is not possible to use uC's, how can connect 2 PC´s and just send ASCII text between them, because every time I connect, I have different IP.
