Bridgeport stepper folks,

Matt sent me a GIF file of Table 4-6, "Axis Drive Signal Sequence,"
which shows the high-low bits that move an axis forward or reverse.
There are three columns: SMD input pin, SMD output pin, and motor lead.
The SMD input pins shows pins 13 and 19 and a two-bit Gray code. The SMD
output pins show pins 4, 8, 28, and 24, and a non-Gray coded 4-bit
sequence. Motor lead pins are 1, 2, 3, and 4 and also show a non-Gray
coded 4-bit sequence.

Which of these should the EMC stepper task generate? I expected a 4-bit
Gray code sequence, but none of these fits the bill.
