To pass data from a phone to a PC based app. can you make a 'data call' to a normal modem from the phone, or do you need to make a GPRS call to a GPRS modem attached to the PC? Does anyone know if it's possible to pass data back over a normal analogue phone line and, if so, how do you initiate the connection? Any documentation that anyone knows of, etc?
Any help very much appreciated!
