How to open correct the serial interface ('/dev/ttyS0') In my program it works for writing, but reading is not possible at the moment. Has someone an idea or example code? Rainer
With USB-to serial Converter the program works (!), but not with the standard 9P serial connector on the mainboard (tested more computers). _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
