Subject: [time-nuts] Lady Heather question


I don't own a Thunderbolt, but I do have a very nice Trimble NTGS50AA
GPSDO which works very well, and it also operates very nicely with
TBOLTMON, in both TSIP and SCPI modes.

However, I've just fired up Lady Heather V2.0 for the first time, and
although the program starts, nothing happens. I have a graph graticule
at the bottom, and a blank black area above with just a few things
written on it, such as the graph legend. No sign of the wealth of data
shown in the help file screen shot, nor any graph data, even after
waiting quite a while.

I tried both the Win version and the DOS version, and they behave the
same. My test computer is an old IBM Aptiva with 450MHz 586 processor,
running Win XP. I use COM2 and the program seems happy with that, and
everything works fine with TBOLTMON.

My next step is to drag out a laptop and spy on the comms between the
computer and GPSDO to see what's going on (if anything). I know this is
a big ask, but any suggestions as to what might be happening?
