That may be because it's emc2 that has this feature. With emc2, you can
assign any function to any I/O, using a configuration file.

You can get emc(1) to swap the step and direction pin assignments by
recompiling. The only change you need to make to the source code is one
line (in emc/src/emcmot/emcmot.c):
change
#undef XYLOTEX
to
#define XYLOTEX

Not too hard :)

Changing the limits isn't too hard, but I don't have specifics on it at
the moment.
This kind of question may be better asked on the emc users list:
