Art,
You hit it right on the head! When I ran dro40a instead of dro40 it
works like a champ :>) I guess it's another case of when in doubt
read the instructions.
Thanks again for your help, now I'm going off line to cut some metal
and mount these puppies on my mill!

Terry,
You may have the same problem that I have and that is the "switch"
that
needs to be set on the parallel port. Have you tried using the
DRO40A.exe
program instead of the DRO40.exe??
This is documented in his text files and you may have to do that.
That is
the only way I can get mine to run also.
Hope this helps, but let me know if it doesn't.

Art,
I need some help here, I put together a circuit using a 74hct14
like you did but I can't seem to get it to work with a computer.
When
I run Steve Linsay's dro40 program it doesn't react to the movement
of the encoders. I've tried it on three different computers,
setting
the parallel ports to both ECP and EPP, there's just no movement of
the readout for any axis. I've tried it in a DOS window under 98
and
booting directly to DOS.
The part that's driving me crazy is that when I hook up the
encoders to a Pwr Sup and a scope I get good square waves out of
the
chip on all 6 lines to the parallel port connector. I've checked
the
wiring about a gazillion times but can't find any mistakes.
Using the parallel.exe program Steve included with his SW, the
ports look good, but when I use his Portstuf.exe hooking an
external
voltage to the port pin 2 and grd pin 22 doesn't have any effect. I
can change the port setting using the keyboard in the program but
that's it.
I don't have any other ways to check the ports that I know of,
but
when I hook a Snappy video capture device to the ports they work
fine.
Any ideas?
Thanks
Terry
