trouble is when i try to upload them back to the fluke always at line 7 fluke sends an error message (Scriptfile about 110 lines long) and aborts sadly the message it gives is the abiguous message AUX-Receiving-ERROR discribed as 'Miscellanious Transmission Problems'????

I'm willing to bet that the Fluke needs to have hardware handshaking that your PIII is not providing, and you are overflowing the Fluke's buffer. I've had that problem with my Data I/O EPROM programmer. I wasn't able to get Win 95 (which I was running at the time) to do the handshaking I needed. This is all conjecture, since I never put a sniffer inline with my COM ports to really see what was going on. My solution was to get a $20 80386 and run DOS.
