As described I am sending 0x0FF000 bytes of data out of the Win7 serial port but only less than a million is counted in the serial receive end of the relaying program. So too few bytes are sent over the TCP/IP link. I think I will have to create a bogus image file where I have a regular pattern of bytes so I can see when the hickups occur in the log. In a normal memory file most of the data is zero, so there are long stretches of zero bytes sent. Therefore it is not easy to see where the losses occur, I only see that the last part of the file (which contains some data) has been displaced to lower addresses. -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
