Communicate with stepper motors?

[Mark Wieder]

Marty-

In addition to what Stephen posted, I want to add that if you *do*
decide to write the low-level stuff yourself, stay away from
setSerialControlString (BZ#1708). What you'll end up with is the port
being reset before each new control value is set, and you'll have
extra pulses in uncomfortable places.
