Thank you for looking this up. I also investigated this, but unfortunately there is no "driver" for the /dev/ttyUSB0. A year ago I used a DataLogic scanner which uses the /dev/ttyACM0 interface, which is a standardized interface defined by the USB organization. Unfortunately, /dev/ttyUSB0 is not standardized but requires different drivers for every chip (e.g. cp2101, ft232, ...). For the MS4407 scanner I didn't yet find a serial driver. So, unfortunately, the RS232 emulation does not work too. :-( Thanks Hansi _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
