Using Asynchronous Terminal Screens
There are three types of async terminal screens.
Menu screens list selections available through the menu system.
Input screens allow you to edit or change information on a screen using
screen function keys (Table H-1, Screen Function Keys) or keyboard keys
(Table H-2, Keyboard Keys).
Display screens show the results from a data collection operation or they
display device-specific information.
The async terminal supports character matching for entering values in fields. For
example, if the values for a field can be
DTE
,
NET
, or
PORT
and you enter a
D
and
press Return (Enter), then the field automatically populates with the value
DTE.
Once an operation is initiated, status messages appear in the last row of the
screen. These include
Please Wait
(when a command takes longer than five
seconds) and
Command Complete
.
