CHAPTER 36
Operation of terminal with keyboard

The VT can provide an automatic sequential display of information mes-
sages on command from the device (see
“Chapter 38 -> Command area“).
The buffer of the Alarm history can be emptied (the elimination of all the
messages registered) only by means of a command from the device (see
“Chapter 38 -> Command area“).
Once the buffer is full, new alarms are no longer registered. You
are advised to consult the chapter Status area of the VT
“Chapter
38 -> Status area for the terminal“
(see also Software Manual) to be able
to tell when the buffer is full.
The format is similar to that of the alarms except that a character [H] is
added in front of the number of the alarm (see the formats of the various
products).
