I bought two TAPR ThunderBolts and on one of them
the serial port would quit communicating after a
while. There was no response to any command, only
removing the power and then restoring power would
get it talking again. My power supply was okay.
I opened the T-Bolt and inspected the solder
connections but didn't see anything suspicious. I
didn't do any further troubleshooting because my
third T-Bolt from Fluke.L arrived and the Fluke.L
T-Bolt has been working fine.
NOTE: If you boot Windows with your ThunderBolt
connected to the Com port, Windows will think it
is a serial mouse and grab the port. It can lead
to some interesting Windows behavior as the T-Bolt
