Hmm... never tried this, but maybe try to look at the data passed through the serial port in ASCII? Possibly the commands are in ASCII, so you would be able to write a driver without having the protocol, with some patience to look at how things are done. -- Oren Sarig sarig@bezeqint.net > I am not actually working in any of these companies, nor have ever heard > anything about the equipment mentioned above.
