KeyScan commands
Sample KeyScan
session
KeyScan lets you automatically scan your computer channels sequentially
without intervention. When KeyScan detects keyboard or mouse activity,
scanning is suspended until all activity stops. Scanning then resumes with the
next channel in sequence. The length of time each computer channel remains on
screen, or dwell time, is configurable and changeable at any time. If you have
multiple units in your system, you can control which units are included in the
scan process. Scanning is halted if the KeyScan Halt command is entered or if
another channel is selected.
The following key sequences configure and control KeyScan. The first sequence
is used to configure the dwell time. The next two commands control which units
should be included in scanning. The Go command enables automatic scanning
with the current computer channel. The Halt command stops scanning. Scanning
is suspended while in Command Mode.
