[BRLTTY] TSI: BRLTTY lost display

[Mario Lang]

Hi.

I've just had a pretty strange error on my TSI PowerBraille 80 that
I've never seen before (with brltty 3.8):

Sep  9 13:12:52 x2 brltty[28789]: Unexpected Response: 40 C0 20 A0 62 E0 00 05 51 08 56 31
Sep  9 13:12:52 x2 brltty[28789]: Input byte missing at offset 6.
Sep  9 13:12:52 x2 brltty[28789]: Unexpected Response: 2E 30 30 37 37 45
Sep  9 13:12:52 x2 brltty[28789]: Display lost after baud switching

It did not reinitialize after some seconds, so I restarted BRLTTY (probably
too fast because I now don't know if BRLTTY would have managed to
reinitialize the display).

Could this have been serial corruption, or something else?

Just in case someone can make something of the log entries above.
