Hi!

Thanks for you reply, Mark.

Unfortunately this seems not to be the case with the PC6K device
support. MSTA seems not to be updated while the motor is stopped. Can
this be considered a bug?

Yes, exactly. Maybe also for a state-machine that implements some sort
of a calibration procedure.

@Ron/Tim/Joe: Can you fix the documentation with the next release,
please? And while we're at it: The Documentation website says "Last
modified: June 25, 2003" which is most likely wrong as well.

Thank you very much,

Martin
