Abstract

Periodically, country representatives request changes to the code page that is used in their country. A code page is a set of visual representations of each of the valid EBCDIC values. Currently, to get a non-programmable terminal (NPT) that reflects the approved changes, the customer must either replace his current terminals with new ones, or a customer engineer must be sent out to take apart the current displays to replace the EPROM or ROS chips inside the display. Both of these are expensive solutions for the customer that, in most cases, require waiting a longer time than should be expected. This invention corrects this problem by allowing the displays to be updated by the system.

Method for Modifying Code Pages and Fonts in Dependent Displays

       Periodically, country representatives request changes to
the code page that is used in their country.  A code page is a set
of visual representations of each of the valid EBCDIC values.
Currently, to get a non-programmable terminal (NPT) that reflects the
approved changes, the customer must either replace his current
terminals with new ones, or a customer engineer must be sent out to
take apart the current displays to replace the EPROM or ROS chips
inside the display.  Both of these are expensive solutions for the
customer that, in most cases, require waiting a longer time than
should be expected.  This invention corrects this problem by allowing
the displays to be updated by the system.

      This invention solves the problem by allowing a code page
change to be downloaded to the NPT from the host system.  This
article will describe the interface between the NPT, the workstation
controller, and the host system that is needed to implement this
invention.

      When a code page is approved, and it is determined that a
change needs to be made available to users, the code page change is
released for the host system.  For example, at a particular release
of the AS/400*, the change will be part of the operating system
software.  When a customer orders the new release of the operating
system, the code page change will automatically be downloaded to
his/her NPTs.
