I have been trying to read RFID tags with the RFID tag reading device connected to RS232 port via COM1 port of the computer. I have already tried Simple Read programme (contained as a sample in javax.comm api) but it only identifies port but cannot read the tag.
I think I would like to write an application or a programme such as Hyper terminal so that I can give some commands to the RFID reader and I would be able to read data.
At the moment I can only read data via Hyper terminal by giving the command which is for continious reading tag mode provided in the documentation of RFID reader device.
Please help me with it as soon as possible.
Thanking you in anticipation.
I'm currently working on some code for an AWID RFID reader. Not sure about other brands but generally you communicate using datagrams, DatagramPacket and DatagramSocket. The AWID unit requires HEX code commands to be packed in the datagram and sent to start reading Gen2 cards. The response is processed in a while loop with socket.receive(packet) and the bytes converted into the card ID. This unit is Power over Ehternet and not on a comm port so it's addressed via an IP address. Hope some of this helps.
Hey , I am reading tags with symbol reader, and i am going to use the byte stream for that.. using singularity as the middleware..could anyone help me form where to start.

I am also working with symbol reader. If you have solved your problem, pls help me. I am also using byte stream protocol. But I am not sure how to get the response from byte stream protocol to String. If you also share your source code that will be really very helpful.
