    Default Reading from Serial port!


    Im trying to make a basic program that reads from the COM1 serial port. Ive tried getting the javax.comm API but it seems Sun has disscontiued it for Windows.
    Tried gettign the rxtx API aswell but all their downloads from their site are corrupted.

    I also got hold of an older version of the Comm API (2.0 i belive) but i couldnt get it to run.
    Ive tried looking everywhere but i couldnt find anything to help me.

    The program i want is something really basic which is gonna read bacicly if the serial port has a 1 on it (its connected to a PIC processor) and then count +1 to a number. I want to use java since im building a Graphics interface to go along with it.

    Anyone have a simple tutorial or something that could help me out, im running on a Win XP machine.

    Or is there maybe someway to get the data from the hyperterminal instead of directly from the serialport?

    If you can do it from C/C++ code, you could use the JNI (Java Native Interface). That link is very detailed, so you might also want to google it. (Sorry, couldn't resist. Haven't used LMGTFY in too long)
    If the above doesn't make sense to you, ignore it, but remember it - might be useful!
    And if you just randomly taught yourself to program, well... you're just like me!
