Thanks Thomas, I changed it a bit and it's in cvs now. Let me know if it
works for you. I have it working with a serial LCD display from WinXp but
haven't tried with linux yet. I also found a [print( message for comport
that wasn't documented before. It will send a symbol as ascii. And someone
else has added a [hupcl( message as well that doesn't work on Windows at
all, so I moved it to the unix part.
