the ftdi chip is practically a usb to serial converter, so you can actually use that. if you look at their windows dll api, you'll see that they've got a set of functions that mimic the windows serial functions. otherwise there are serial comms units for fpc (but i haven't used any of them). henry _______________________________________________ Lazarus mailing list [email protected] http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
