View Error Table
Use the ERRT command to view the table of possible transmitter errors.
The table includes error ID, error count since last reset, level, current
state, and error text. Most of the errors can be seen also on the display
(see Table 12 on page 76) but there are some that can only be viewed on
the serial line.
