Here is a link to a HyGain document: <http://www.hy-gain.com/man/pdf/DCU-1.pdf>

Here is what it says in the Idiom Press manual for the Rotor-Ez that I have:

HyGain DCU-1

4800 baud, 8 bits, no parity, and 1 stop bit.

APlxxx<CR> sets target bearing to “xxx.” degrees where xxx are three digits between 000 and 360, and executes. A typical 
command to rotate to 080 degrees would be AP1080<CR>.

APlxxx;  sets the target bearing but does not execute.
AM1;     executes rotation to the bearing set by the AP1xxx; command.
AI1;     inquires current bearing; and responds with (000-359) degrees
;        terminates rotation
