I have a device which connects via serial port. I communicate with it via Windows Hyper Terminal. I'm just wondering, what protocol does it use? As you probably, know hyper terminal can display and accept input as well. It's a two way communication.
Thank you for any help.

There is actually no protocol. Serial sends and recieve bits. You specify them in your serial setting when you want to communicate with a device. Typically 8 bits are specified which is equivalent to an ASCII character. Both communicating parties send and receive ASCII data any time they want
