Well as you can see I don't. However, I have not had any problems *receiving* data from the remote server (this is where the SerWrite would be used to send it into my Win7 program). What I see is losing data when sending to the server, i.e. not all bytes on the wire from the Win7 program are actually received by my relaying code: SetLength(Buf, BufLen); LenRd := SerRead(FComH, Buf[0], BufLen); Here data are arriving but some are lost, so the total number of bytes relayed are too few. THey are not lost on the TCP/IP outgoing side because I am counting and showing the number of received bytes and this counter does not ever go above 1000000, it stops somewhere at 970000 or so. >if SerWrite(FComH, Buf[0], Length(Buf))<>Length(Buf) then Raise >Exception.Create("KBOOM"); -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
