Bob,

Great idea... I now have my TBolt connected to 2 different PC's via a serial Y cable using two different USB-Serial adapters.. both PC's running LH and logging in background.  Now to see if both crash simultaneously.

Hi

If you have a second PC, there’s a real quick shortcut. 

Make up a Y cable and log the output of the TBolt on the second machine. If the TBolt really *is* sending junk, you’ll see it. If not, the TBolt is ok. Swap the machine that is logging, if the same thing is still true, it’s not the TBolt and it’s not the serial “stuff”. 

Bob
