A method of displaying an image in any session of a multiple display session non-programmable terminal is described; the non-programmable terminal is only capable of displaying and storing a single image. Also, a method of saving audio and/or video state from a non-programmable terminal and later restoring to the same state is described.

Non-Programmable Terminal (NPT) can provide the ability to
display a single monochrome image/fax on the display screen. The NPT
may be able to store and process a single image/fax at any given
time. The NPT could support multiple display sessions which appear
as independent NPTs to the host system. This disclosure describes
how the end user could display an image/fax in any session.
The following functions could be supported:
o At NPT power-up, each session could indicate image and fax can
displayed on this session. The host system generally queries
functional capability of each display session, now including
support of the display of image/fax.
o The NPT could store and display an image/fax in any session
receives an image/fax if an image/fax is not displayed in
o The NPT could not store an image/fax if an image/fax is
in another session (no disruption of the image/fax in the other
session). The NPT could automatically send (no user
required) a new event to the Workstation Controller (WSC)
specifying that another session currently has image/fax
o A new AID value (normally AIDs indicate keystrokes, like Enter,
Help, and the command keys) could be defined to indicate that
image/fax was not displayed in the this session because there
an image/fax displayed in another session of the same physical
display. The WSC could send this new AID to the host system.
o The host system could write a screen text message to the display
session stating that there is an image/fax displayed in another
alternative is for the NPT to display the new image/fax
in the current session (and remove the image/fax from the other
session). When the former session is made active again, the display
could generate a new event to the WSC which generates a new AID
requesting that its former image/fax be resent. The host system
could then resend the image/fax to the display which would then
process and display it.
The NPT could
have the capability of displaying a video window
and/or providing audio output with the help of an external TV tuner.
The video and/or audio is provided by an external source. A host
application could control the video and/or audio by sending data
stream commands through the WSC to...
