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.
