When you plug in the module via the supplied USB cable, you should notice an additional serial port becomes active on your PC (for example, COM3). You can check which port it is by going into the device manager in windows (right-click MyComputer, select Properties, go to Hardware/Device Manager, expand the Ports item.). You can now communicate with the device with any serial communication program (such as HyperTerminal, which comes with Windows). The serial port settings are 115200 baud, 8 data bits, no parity bit, 1 stop bit, no flow control. The general formats of the commands are as follows: $
