    Nothing a bit of research wouldn't cure either.

    I can give you a idea about, but i dont have any code for this.

    See everytime data transfer occurs it happens through a file. Means, u write on a file and device connected from com port reads data from that file. same happens vice versa when u hav to read some thing from com port.

    Some basic steps are initialize all ports of COM. then set some flags and then start reading and writing.

    i hope this much can help you out.
    S_ccess is waiting for u. Go Ahead, put u there.
