IBM 3174 Reference Guide

Using Your ASCII Terminal
Attention Fields
An attention field is identified by a space, a null, or an ampersand (&) in the first
position of the field. Place the cursor anywhere in the field that you wish to signal
as an attention field and then use the Cursor Select key sequence. When you use
the Cursor Select key sequence and the cursor is in an attention field, information
about all fields that you have either selected with Cursor Select or modified with
normal keyboard input is transmitted to the host program.
ASCII Display Host Addressable Printer Support
A printer connected to an auxiliary port on an ASCII terminal that supports remote
access to its auxiliary port can be defined as a second host-addressabie logical
terminal on the 3174 port to which the terminal is connected. You can then use the
printer in system mode. This support operates only when you are using your ASCII
terminal to communicate with an IBM host.
If a printer is connected to an auxiliary port on a display and is not defined to the
3174, the printer can be used only for screen copy operations that you initiate.
Screen copy must be a completely local function.
The foliowing terminals support the ASCII Display Host Addressable Printer:
ADDS Viewpoint A2, /78** (forthe Model A2, only an ADDS Viewpoint printer
can be used)
Cedar", Cypress", and Juniper" terminals
DEC VT101" (as a VT100)"
DEC VT131" (asaVTlOO)
DEC VT220" (as a VT100)
DEC VT240/1"
Esprit 1078"

Input from devices that are connected to the auxiiiary port of a display is not
explicitly supported: any such input is assumed to be from the display.
