Many thanks, it will be useful. :) But some questions popping up: In the patch report you write SerFlush() is non-destructive and the new SerFlushInput/Output() are destructive. What does this mean exactly? >From my memory using "flush" on a file descriptor is used to force writing the pending contents through to the disk or file or whatever is connected. Regarding serial ports there mostly is a hardware function for emptying the read oder write queue while throwing away anything in there. Is that the difference in the flushing you're talking about? -- Marc Santhoff <m.santh...@web.de> -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
