// # Product name: GPS/GPRS/GSM Module V2.0
// # Product SKU : TEL0051
// # Version     : 0.1

// # Description:
// # The sketch for driving the gsm mode via the USB interface

// # Steps:
// #        1. Turn the S1 switch to the EN(right side)
// #        2. Upload the sketch to the Arduino board
// #        3. Turn the S1 switch to the communication mode(left side)
// #        4. Turn the S2 switch to the USB side(left side)
// #        5. send AT commands via the Arduino Serial monitor
