x -
The X indicates the computer associated with the
active session is not available. This indicator will come
on for short periods of time whenever the ENTER key is
pressed. Don't be alarmed.
If the indicator remains on for a long period and no
activity appears to be taking place, there may be a
problem with the computer. Please refer to 'What To Do
if Something Goes Wrong' later in this chapter.
• Inhibit/Insert - The Inhibit indicator is controlled by the
computer associated with the active session. If the word
Inhibit is displayed, the keyboard is locked and input is
inhibited. This indicator is normally on when the X is
also on.
The word Insert indicates the INS key was pressed and
the keyboard is set to insert mode. All data will be
entered at the position of the cursor and all data to the
right will be moved to the right. Press INSERT again, or
the RESET key (or any key that causes communication
with the host system - ENTER, PA keys, PF keys, etc.)
to turn off the Insert indicator.
Note: VM/PC 3277 emulation does not require you to
set nulls on before you can insert characters into a line.
n session name - The n session name indicator is the
number and name of the active session. The number and
name displayed are the same as the number and name on
the Session Selection Menu.
