I am using BCB6 so I hope this is the right forum. I am using asyncpro's TApdComPort component for serial communication. I need to send 12 bytes and receive 22. I can send the 12 bytes using putblock(..). But I can't figure out how to reeceive my data.
Also, I would like to sync the receive and send so that I send only when I receive. I guess I can figure that out if I know how to receive.
