Taig mill, Taig controller, EMC setup?

I've got EMC up and running using BDI 2.11-01. It's working great, as far
as the computer goes. I can't get my mill happy with it, though.

Right now EMCMOT is using steppermod.o. It looks like the pinouts for
this are:

Pin Function
2 X Dir
3 X Clock
4 Y Dir
5 Y Clock
6 Z Dir
7 Z Clock

Only problem is, the Taig motor controller isn't set up for
direction/pulse, it's set up for phase output:

Pin
2 X1
3 X2
4 X3
5 X4
6 Y1
7 Y2
8 Y3
9 Y4
1 Z1
14 Z2
16 Z3
17 Z4

Not really compatible...

I saw some tantalizing information at:

http://www.mindspring.com/~pitt/EMC/EMC_docs.html

This seemed to imply that the pinouts for freqmod.o were quite different
from those for steppermod.o, and that the pinouts for freqmod.o could be
changed using this bit in emc.ini:

[EMCMOT]
EMCMOT = freqmod.o
STEPPING_TYPE = 1

Unfortunately, that's the only mention I've seen of the "STEPPING_TYPE"
parameter, so I haven't been able to find out if this will get me up and
running, or if different values for STEPPING_TYPE produce different
pinouts.

To make a long story short, has anyone with a Taig mill, using the Taig
motor controller, been able to set up EMC so it's happy?

I'm quite willing to start munging around in the code either to answer my
question or to patch it so it'll work. But if this has already been done,
I'd just as soon skip that part and get back to machining. ;)

Thanks,

Tom
