The USB converter has been use in this project because of the GSM
modem itself only be able to connect with serial. The USB converter to serial
extremely need to connect the server to GSM modem. After hardware been
connected, hyper terminal application take over to drive the connection. To make
sure the connection really establish. Hardware and software communication port
of number must be the same. Communication port known as COM port can verify
through the device manager. From there, the number of COM port will be know. The
later on, set up the connection using the hyperterminal same with. In hyperterminal,
to make sure all the parameter in properties of connection according to need. The
most important parameter are baundrate value that is 115200 bits per second
should be select and flow control must be select to hardware. This parameter is
required in order to establish the connection. ASCII format also need to set in
ASCII set up in order for the format to work. Make sure all the parameter
selected as required. After all the connection and parameter has been setup,
the command can be apply in hyper terminal window.
