error setCommConfig?

[starzstone]

hi,

i've seem to have problem with this line of code:

try{
serialPort = (SerialPort)portId.open("Serial_Communication", 2000);

} catch (PortInUseException e)
{
return InitFail;
}

when the program is run, there will be an error "Error 1 setCommConfig" what causes this error? im using the java comm package by sun.

pls advise. thanks.
