Using Async 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) or keyboard keys (Table H-2).
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.
