Locate the freqfunc function within emcmot.c... Find the vomment that says
"timer expired -- do the down transution", and a few lines further down, "do
the up transition" - Transpose the loByte and hiByte operators, then
recompile.

You may find it quicker and easier to use a TTL inverter on the parallel port
if you're not familiar with C.
