Chip,
This is exactly how I have the limits set (plus the estop).  All are wired in series.  All NC.  If I hit one of the limit switches (with my finger), all the LEDs light in the configuration window.  If I let go, they go out.  But it won't reset.  It says "external estop requested" and scrolls "press reset...emergency mode active".
Here is the port 1 pin state in the configuration window (x=on, o=off):
ooo*********oxoooo
oooooooooooo

If I hit the limit switch (capital X comes on):
ooo*********Xxoooo
oooooooooooo

Chip,
The parallel cable fixed the problem.  So the serial printer null modem cable was the problem.
Now that the motors are moving, I have a new issue: I can not get the program to reset without bypassing the estop and limit switches.  I have 0 volts on the limit switch circuit.  It goes to 5 volts when I open the sircuit (hit the limit switch).  Active low is not checked.  I see the pin LED light (in diognostics) when I open the circuit, but it will not reset.
Any ideas?
Thanks for the help.

I'm reading 3.42 TO 0 volts on the parallel port out of computer.

                   PIN 2   PIN 3   PIN 4   PIN 5   PIN 6   PIN 7
X-  ARROW LEFT   0.03V   3.42V            
X+  ARROW RIGHT   0.03V   0V            
Y-  ARROW DOWN         0.07V   3.42V      
Y+  ARROW UP         0.07V   0V      
Z-  PAGE DOWN               0.07V   3.42V
Z+  PAGE UP               0.07V   0V

Put the question in the wrong spot. 
The jumpers are there.  I checked Sherline 1/2 step mode.  Nothing.
I only have X stepper connected.  I hit Y and Z jog.  X moved in same direction with both  Z up and Z down (pg up and down).
Tried it again with  Sherline 1/2 step mode off, nothing.  Turned on Sherline 1/2 step mode again, now nothing.

yes, 0x378.  Check same on parellel port in hardware.

Just starting.  Xylotex board.  Double checked wiring.  Vrefs all 1.86V.  VBB 24.8 V checked.
Set X, Y, and Z for pin 2, 3, 4, 5, 6, 7 Step Dir.  Can't get limit switch ( when switched) to show on Diagnostics.  Motors won' jog, although the position DRO moves when arrows pressed. 
Tried Paralell Port BIOS settings of output only, bidirectional, EPP, and ECP, with no motro action on any.
Can some one point me in a direction?
Thanks,
