I expect it is just returning the actual encoder readings not converted for the mount attitude.
Correct ( almost )
The raw encoders are converted to normalised "base relative" values.
To report the Alt/Az when polar, these need to be transformed.
When viewing via the hbx, this conversion is done properly
but via rs232, the raw base relative coords are sent instead.
Ie down here, in polar, a 497 will report Alt as -ve (DEC)
