[time-nuts] Configuring LH5 for use with an HP 58503A

I just resurrected an HP 58503A and have been using it successfully for the
last few days with the GPSCon program. I would prefer to use Lady Heather,
but can't seem to get it configured properly. My system is a Windows 10 PC
with a USB to serial cable at COM3. The serial protocol on the 58503A is
I've added /3 for the COM port to the startup command line. All other config
file parameters are unchanged from the default.
When I start LH it finds the 58503A and identifies it as a SCPI receiver,
but then it hangs with no position data or time data, and the PC speaker
chimes continuously at slightly slower than once per second. The only way to
exit the program is to kill the process with the task manager. There are no
other programs vying for the COM port.
Any and all help is appreciated!
