Pass Thru allows terminals and printers attached to an HP 3000
to emulate IBM 3278 display stations and 3287 printers. You can
use Pass Thru for direct access to IBM host applications, without
programming the HP 3000.
This chapter explains how to create a Pass Thru configuration
file, called PTCONFIG. The PTCONFIG file defines the functions of
your configurable terminal function keys, or rolling softkeys. It
also specifies other Pass Thru options, described in this chapter
under "Elements of the PTCONFIG File."
Rolling softkeys, their default functions, and their user-defined functions
are described in Chapter 5 “Using Terminals with Pass Thru”
