[fpc-pascal] serial ports under Unix using Freepascal

[papelhigienico at gmail.com]

Hi!

I'm creating a component that handles serial port in windows/unix. Under
Windows I include in uses the unit windows, that open, close, read, write,
test if the configuration of serial port is valid (some set of
configurations of baudrate, stop bits and parity is invalid in windows)  and
if serial port exists.

Under Unix I found the unit Serial, that open, close, read and write. How to
test if serial port exist? Unix accept any set of configurations of  the
serial port? I see fpopen that return the handle of serial port but I not
found anything that describes error codes returned by this function in fpc
rtl documentation.

Somebody have tried to do this?

info: I newbie in FPC Unix (FreeBSD).
