[amsat-bb] Tracking - End-stop Problem

A problem that I've had for many years is how to track when the
satellite's azimuth crosses across the rotator's end-stop, ie. when the
azimuth changes from 0 to 359 degrees.
My rotator turns between 0 and 450 degrees, so it should be possible to
use angles between 360 and 450 to overcome a sudden transition
from 0 to 360 degrees.
As the pass data is available within the tracking program, it should be
feasible to deal with the problem in the program. Do any tracking
programs include this feature?
A possible solution would be to use a small PIC between the computer and
tracker, which could modify the commanded azimuth.
I'm using a Yaseu 5500, LVB tracker, Sat_Explorer tracking program and
Any help, suggestions or comments would be most welcome.
