  • RS-232 is not a protocol - it is a specification of the electrical properties of the hardware interface like signal levels and input impedance - see chapter "RS-232" of my SerialPort tutorial.

    If you don't mind VB examples, the tutorial describes how to send and receive bytes through the serial port.

    On top of this you need a communication protocol. There are several possibilities where the simplest one is an ASCII protocol where each telegram is terminated with a given byte - usually LF or CR. What do you intend to do?

     

     


    Everything should be made as simple as possible, but not simpler. Any fool can write code that a computer can understand. Good programmers write code that humans understand.
