hi,
I am just 1 week conversant with usb and dont know much details. I am
writing a program to communicate with GSM modem connected to PC with
USB cable.
No matter which AT command i send to my gsm modem, it returns the same
2 byte response to me. Response is 1` (0x31 0x60).
Are you sure that you should send the AT commands directly? Have you
snooped any working sesion with the modem to see if you first need to
send other initialization data?
