Hi Anthony,
I was getting that error, then "communication established", then some rapid fire procession of error messages that I didn't write down, then back to "trying to establish communication".  It's probably something simple like a bad cap, but it was still under warranty, so not my problem.

I have both versions of SatStat (the HP and the Symmetricon).  Both are set for COM1 9660, 8, n, 1.  Both are running in an XP VM.  I have tested the virtualized to physical COM1 connection using a terminal program and a scope, so I know that works.  When I select Port Open, I just get "Trying to establish communication". I never see the SatStat info page.

If I use the terminal program under XP or on the Win7 host, I can send *IDN? ,  :SYST:STAT? etc. but never get a response.  Although I can see a response by scoping the cable - it peaks around 4.5v, and is quite noisy.  My suspicion is that it's the noise that is causing the trouble.  AECI are sending me replacement units, but if you have any ideas of other things to try, let me know
