Error Log
The list of the six most recent errors is displayed. The newest error is
displayed in position one. In a full log, position six is the oldest error. If
more than six errors are received, the oldest error is discarded. If a
position is all zeros, then not enough errors have occurred to fill up the
log to that position. When a new error is received a check is done to see
if that error is identical to the last error received. If so, it is not recorded.
Identical errors may appear in the log if there were intervening errors.
The following error messages are stored in the error log.
