[Dxbase] Rotor Interface Problem / Hy Gain DCU-1

[JNMazzoni]

I am having trouble controlling the Hy Gain DCU-1 from DXbase 2005.  I cannot move the rotator from DXbase.

I can control the rotor directly from the DCU 1, I have the jumper connector on the EXT connector of the DCU-1. 

On several occasions, not always,  I received the error message " The beam heading information cannot be found in the summary window" 

My computer is an IBM think pad with a port replicator. The computer tells me that com 1 is active and working but I have nothing else to connect the serial port to for a test.

Any help??
