Explanatory comments
This command returns a variety of boolean status values as follows:
strack tells whether sidereal tracking is on.
drives tells whether any drives are on.
dalt tells whether the elevation drive is on.
daz tells whether the azimuth drive is on.
drot tells whether the rotator drive is on.
dbldg tells whether the building drive is on.
cbrake tells whether the elevation cell brake is set.
mbrake tells whether the elevation motor brake is set.
stpin gives the elevation stow pin status in a curious way.
The first variable tells if the pin is in.
The second variable tells if the pin is out.
(It can be neither meaning it is in motion or faulty).
 | Having two values returned for stow pin status is bad, this will be changed in the next revision of the protocol. |
