Are you sure you don't mean GPS? The GPRS protocol doesn't have coordinates,
unless you send some...
Anyway, for GPS, if your device supports NMEA183 (most devices do), simply
read the serial port (it is working at 4800 baud, no parity, do
handshaking). Use VISA so it stops reading when it encounters a \r (or \n,
not sure). Then, parse the string. Use Format From String for that.
