Notes
• "Automatic Laser Control" does not compensate
for an explicit change in mark speed between two
Mark Commands caused by a
call.
• "Automatic Laser Control" and
not affect the same output port at the same time.
• "Automatic Laser Control" cannot be combined
with variable laser control via the
McBSP interface (see set_multi_mcbsp_in).
