Hi Micro:You can use general 56K modem driver for it. It should work. You can use DTE speed up to 115200bps. For AT command set it is included inside of CD. Please looking into CD manual under GPRS modem section. I also attached this file. Salve a tutti qualcuno puo' darmi una mano nel capire questa mail? Grazie.Dovo cercare di istallare il modem GPRS.
