Setting up RFID reader.

The Senor sample RFID reader we have came with the iSPOS series of touch screen computers. In these systems the com ports are set up as follows:

Since in Linux the default kernel behavior is to only support 4 serial ports, we have set up the following:

In order to communicate with the RFID reader, we need to send it an initialise command (this will cause the device to beep): 

send      01 03
response  01 01
send      01 03
response  01 01
send      02 0b 0f
response  01 00

send      02 02 26

You will get one of the following responses: Detected a S50 type tag respons
