[time-nuts] Thunderbolt serial port problem

[Mike Naruta AA8K]

Search the archive for the subject:  "Thunderbolt repair"
and "Thunderbolt quits".

Brian found a bad voltage on his power supply.

Perhaps your PC's power-saving feature?

Is your Microsoft Windows serial mouse feature disabled?

If it is not communicating at all, have you tried a different 
baud rate?



I have a TAPR Thunderbolt that quits talking out the serial port 
after a period of time.  Only a power down reset gets it 
responding again for a while.  I haven't opened it up yet; I 
bought one from fluke.L to get back on the air.  The new one 
works fine.
