Identifying Physical Location of Port-Sharing Devices

      This invention discloses the extraction of a user-specified
imbedded string on a device attached to a system, and the
presentation of that string to a user interface of that system.

      Certain asynchronous devices have the capability to configure a
terminal identifier residing on the physical display itself.

      An ASCII workstation controller (WSC) in the system polls the
device with a request for this terminal identifier, receives it from
the display, and passes it up through the various layers of the
system.  The port-sharing code receives the terminal identifier and
translates it from ASCII to EBCDIC.

      This terminal identifier is then stored in the associated space
of the device description.  An application programming interface
(API) has been created to allow user applications to gain access to
it.  The user applications can take advantage of this terminal
identifier for determining which physical display the device
description actually represents.
