  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 configuratio=
ns 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  th=
e 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. =
