    Hello
    I want to send data strings via COM1 to a gsm Modem m20 (Siemens).
    Sometimes it's by random I got the error:
    java.io.exception: write error
    at com.sun.comm.Win32SerialPort.write

    Somehow if I flush the OutputStremWriter:
    at java.io_OutputstreamWriter.flush(Unknown source)

    Can someone help plaease?

    Thanks
    Michael
