Abstract

Some computer systems support the buffering of keystrokes, which is referred to as the Type Ahead function. This keystroke buffering capability is sometimes desirable and sometimes not, depending on user preference and effect on application programs. Described is a method for enabling users to customize this Type Ahead function.

Customization of Workstation Controller Type Ahead Function

      Some computer systems support the buffering of
keystrokes, which is referred to as the Type Ahead function.  This
keystroke buffering capability is sometimes desirable and sometimes
not, depending on user preference and effect on application programs.
Described is a method for enabling users to customize this Type Ahead
function.

      Some computer systems support the buffering of keystrokes,
which is referred to as the Type Ahead function. This keystroke
buffering capability is sometimes desirable and sometimes not,
depending on user preference and effect on application programs.
This article describes a method for enabling users to customize this
Type Ahead function.

      Users can manually turn Type Ahead on or off via a Hex-K
keystroke combination (toggle function).  This manual intervention
must be performed on each attached display after each system
power-up.  If there are multiple users per attached display, the
state of Type Ahead is unknown when a user signs on.  The user must
manually determine the current state of Type Ahead via Hex-M
keystroke combination and message line indication, and manually
change it if desired.

      Type Ahead can be turned off for all devices attached to the
WSC via a Hex-X keystroke combination.  However, using the Hex-X
control can potentially cause disruption to other users on that WSC
who want Type Ahead to be on.

      When Type Ahead is active, the Attention key is buffered.  Some
applications use the Attention key to perform immediate recovery
tasks or to perform user interface functions.  If the keyboard is
locked during an IBM 3270 emulation session, the Attention key will
be buffered, which disables user access t...
