[TRLog] rotator control

Had the pleasure of hosting Bob, W9KNI of Idiom Press 
at the contest station last Monday. I have several of his
TailTwister positioners (Rotor-EZ) installed with the  RS-
232 control port. They work great in that you can select
a direction and quickly be hands free.

During our conversation we talked about TRLog controlling
the rotator, a feature I do not use. It doesn't seem useful to 
me and have never tried it. 

I connected a controller to a serial port and found TRLog 
runs the rotator just fine, JA sent it to 275, UA3 went to 
356 and CX1 sent to 105, right on the money. 

So I have the following questions:

Would it be of some interest to have TRLog control more 
then one rotator? 

Turning three antennas in a 4/4/4 stack to the same direction 
with the Ctrl P command would be useful. It would suck up
serial ports with Rotor one = serial one style assignments
but maybe a Rotor # control bit or using a LPT port. The 
Rotor-EZ kit uses a socket IC for upgrades. Maybe a 
serial port rotator address could be added to the command?
All this may be academic as the serial port may work going 
to two controllers in parallel, I will check that out.

Would it be of any value to have the program read the 

The command is "al1;" but of limited value as most everyone 
has the controller in front of them. I have a unique problem 
where I have some controllers behind me when my multi-op 
station is configured for SO2R.

All this requires programming (time) and I don't want to waste
the resource on something of limited value. Still, controlling 
a stack would be "cool" and now that everyone has them,
maybe doable.

I see the Orion port command but also the rotator type
command?? Looks to be the same thing to me..
