Thanks for your reply.

I'm using an oscilloscope to look at the signals coming directly
from the PC, so I'm fairly confident I'm don't have anything
swapped. I used another script to verify the pins were electrically
OK.

I'm using the freqmod driver. I don't have the STEPPING_TYPE set, so
the driver is suppose the default to the step/dir format. Also, the
IO_Show utility confirms what I'm measuring with the scope. If I had
to guess, I believe I have something incurrately specified in my
emc.ini file. Maybe the program thinks the axis is at some limit?
When I installed the EMC, I had to change several polarities. I
don't get any messages, the motor/signals simply refuse to move in
the + direction.
