Can you please zip up the results directory any time you get a failure, as well 
please attach the files you are running if they are different.

This may help pinpoint where the failure is occurring, and suggest where some 
debugging code is necessary.

Looked at those,the reason I need the logs as well as a snapshot and the 
console output is to determine if the failure is happening as goterm finishes, 
or afterwards.

I have had no failures in goterm in 30+ builds now, so I am suspecting 
something else is going on, but I need some data.

If you can repro a failure, the data will help isolate the issue.

As for the buffer size, the driver on the PC should have ample buffering and 
should not overrun the ic's buffers. My testing however indicates there is some 
problem somewhere, and the buffers can be overrun. The symptom was a single 
dropped character one every 3 hours or so running at full speed.

With the changes to the buffer size and a delay, I have never seen this failure 
again. The change in the buffer size alone did not eliminate this issue.

Given the behavior I suspect there is a boundary issue in the driver.
