Hi,

I worked on troubleshooting the programmer yesterday.

The puzzling thing I found was that running the Programmer software
does not have any effect on the port pins of my laptop computer. I
connected an analogue multimeter to the port pins, particularly D1,
which is the Clock, hoping to see some deviations, when the software
was run. However there were none. I then checked the other pins.
Results were the same.

Any ideas as to what is happening. I have an HP printer installed
on this port LPT1(378)
