I think Bob, W7LRD, and I have a common block to some of our computer 
applications.  I am in the process of getting my G-5500 rotor, LVB 
Tracker, and IC-910H to all play nicely with one another using SAT32PC 
software (v12.8).  I am using a Panasonic Toughbook Computer with the 
serial port (com4)  connected to the ICOM CT-17 level converter for 
frequency control of the IC-910.   A USB port (com1) is used to talk 
with the LVB Tracker.  Frequency control works terrific.  I cannot make 
the rotor control work however.  The LVB Tracker manually controls the 
rotor just fine.  I can also control the rotor position by opening a 
terminal window and giving commands(which indicates to me commands are 
going down the USB pipe).  When I give a park command via SAT32PC, 
nothing happens nor does the rotor respond to other movement commands 
from the SAT32PC software.  I know I must be overlooking something very 
simple and perhaps a good nights sleep might help me to resolve my 
problem. Can someone share the "secret" of rotor control with me?  
Hopefully no secret handshakes or needed.  Any help will be sincerely 

soon to be an ex "one armed paper hanger" in the satellite arena
