This command disables or enables the Alert Option on the Ultima X
unit. This is a single byte containing a 0 if disabled or 1 if enabled. If
enabled, the Alert Option will cause the 4-20 mA to be set to 3.75 mA
during calibration of an Oxygen sensor (if the Cal Signal Option is also
enabled). If the Alert Option is disabled and the Cal Signal enabled, the
output will be set to 21 mA during Oxygen sensor calibration.
