Try to test the interface by using a battery on the line that would be DTR.
If you can key it that way then you interface is ok. If not, you may have a
shorted transistor or other problem.
Next get a digital meter (or a good analog meter) and put it on the DTR line
to see if it is switching when you key. If it is not you have a setup
problem in WriteLog.
One thing I can assure you is that it is NOT the fault of WriteLog (properly
configured) and it is NOT the fault of WIN2K as I used it on WIN2K..
You cannot use the LPT port to key on WIN2K or WINXP without a driver which
WriteLog has not deemed a necessity so you would have to use a third party
driver but that is not your problem if you are using a com port.
