free pascal and serial ports under linux

Hi all,
Im just trying to find possibilities to read/write from serial ports under
linux with free pascal. I was surfing the net and all I found are thousands
of Windows and DOS-working units, but nothing to be used with Linux. I am
using Red Hat 7.2 and free pascal and I would really appreciate if someone
could give me at least little hints on how to talk to my serial port ...

thanks a lot for any help
Andreas

This is not a Delphi question nor a database question. Perhaps you
would be better off asking in a more appropriate forum? Anybody got
any ideas? Are there FreePascal newsgroups?

I agree that this is not the best forum to post the question, but the simple
answer is that in Linux "everything is a file."  You'll find a file under
the "/dev" directory which corresponds to the serial port device.  The name
can vary from system to system.

It's a "character" (vs. a "block") device because the data passing through
is viewed as "a stream of bytes."
