Thanks to all. I am using a high end laptop running Windows 7 Pro, power settings are all max'ed for performance - no sleep modes. I thought it had a direct DB-9 serial but it does not so have to use an adapter. I have 3 different manufacturers USB-Serial but all use Prolific which I heard has counterfeits and driver problems. I just ordered an FTDI type recommended for my Flex radio. Fingers crossed not the TBolt.

Jerry,
I agree, if you have a "real" RS-232 port available use it to check if the TBOLT and LH communicate. If that works, then USB adapter is suspect.
Prolific has been problematic. When I had problems with my Prolific adapters failing, usually after an "update" - particularly Windows - I switched to FTDI adapters and have never had a problem since.
