I solved an issue connecting TBolt directly to the PCIe Serial Card.
Previously I was using DigiKey PortServer device. Strange that it was
working OK for long period of time.
May be some recent MS update did something for the driver. Will
investigate it later.
Now I could see the sat. information on LH screen. As well there is no
"empty screen" any more ! Thanks everyone for support !
Regarding the date/time - personally I am using "chronyd" with 1PPS
interface via RS232. This setup works perfectly fine for my lab.

But the TBolt will not ever on its own be correct.
For frequency and 1 pps not an issue. For NTP unfortunate.
By the way my TBolt fired up and tracked satellites without any
It would be nearly trivial to write a t-bolt specification reference
clock for NTP. The driver would correct the date the same way LH
does. Maybe six lines of C code max.
