[time-nuts] Is there any way to recover if one messes up serial port on settings on HP GPS receivers?

Thank you Tom. I had assumed that the serial port settings would be
preserved in the event of a power failure.

As I reported a week or two ago, Lady Heather will not communicate well
with the receiver. I wondered if there was any point in trying a faster
serial port speed.

Lady Heather gets the time from the GPS receiver once, but then either

1) Windows reports the program is not responding.

2) The clock runs backwards.

I thought it might be worth trying different serial port settings.
