Jim: I would have tough that the signal strength was a function of the hardware and not software. I am trying to figure out how you can adjust signal strength to the serial port with software and I cannot come up with an answer. It would seem to me that maybe your problem was due to the serial port on the new computer and not necessarily the software. Old serial boards had larger components and generated stronger signals, new board tend to be tinny and likely have weaker signals; also, cable length, AWG and impedance have a large effect in serial signals. If the problem is with the operating system, should you not have the same problem with all the serial ports? I used to run into the same problem with switches and parallel ports, manufacturers told you not use them as the may actually damage the printer (HP's advice for laser printers); however, they work perfectly in practice and you would run into problems only when you were using it with a laptop running on batteries, as soon as you plugged the adaptor, it would work correctly.

We just ran into a good one. We replaced one of our computers on our plant floor - Win98 with a W2k machine and ran into problems getting this machine to talk to the CNC lathes,mills and devices that the Win98 machine had been talking to for years. We troubleshot a gazillion things and come to find out that since we had a switch box so this machine could talk to different CNC devices that it would not work through this setup. After some research one of my colleques found that the signal W2k sends through the Com ports are not as strong as the Win98 machine, and I was told that this is how good ole MS created it.. Most likey the same in XP. We eventually had to dump the switch box and add on a serial port card so it could talk directly to get it to work. Apparently the switch box produced just enough resistence that it could read info from the CNC machine, but not send to it.. Thought this might help someone, sometine, somewhere Jim Limburg Javier Valencia wrote: > A couple of observations.
