I've been doing testing with my parport jumper board. I'm not getting
any state changes when E-stop is on, or off, or machine on/off. Yes,
my par port is working and EMC is reading it (limits switches work, as
confirmed by EMC and IO show). I can 'hot wire' my controller by
jumpering pin 16 (EMC) to pin 14 (controller). Motors get power and can
be jogged around (step/dir working fine). However, the motors have
power no matter if EMC estop is on/off or EMC machine on/off.

I retested with MACH 2 and estop off turns on power to my motors,
estop on turns power off. I can enable my hi/lo power to my steppers,
everything works and I can see the state changes when estop is on/off.

My problem is in EMC, somehow my estop/machine on/off switches are
not configured to my parallel port. What the heck am I doing wrong??
