  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.
