can anyone help me to write the C++ program to send command using RS232 to RFID(omron reader V720S-BC5D4A) to read the tag continuously? i am a very new to this RFID inviroment and my supvisor ask me to re-code the program for that reader. i have designed the antenna for reader and i need to measure the SWR values, and in order to measure the SWR values, the reader needs to transmit the singal at all time. the existing program is to transmit the signal at toggle mode so that i need to re-code the program but the existing program is in java and unavailable. the command for the reader to transmit the signal constantly is " 00RDSRAA0001", but i don't know how to put that command using C++ program.. i will be using RS232 (com2), baud rate: 9600, parity : even.
