Using the Keyboard Maps
How to Use the Keyboard Maps
This appendix contains a full set of keyboard maps for ASCII and 3270 terminals
supported by the 3174 Establishment Controller. These keyboard maps allow you
to:
• Use the correct keys on an ASCII terminal keyboard to obtain 3270 functions.
• Use the correct keys on a 3270 terminal keyboard to obtain ASCII functions.
If you use several different ASCII terminals on a regular basis, however, you may
find It easier to use the universal keyboard map, so that you do not have to
remember the specific map for each keyboard. The universal keyboard map Is the
same for all display station types, but the correlation between the real key and the
mapped key Is not always as obvious as It Is In the specific map for each terminal.
If you choose the specific map when you are connecting to the host, and later find
that you want to use the universal map, the universal map usually works.
For 3270 terminals being used as either an IBM 3101 or an DEC VT100, the
keyboard map you use depends on the 3174 configuration question 702. The
keyboard map titles Include the response to question 702. Consult your system
administrator to find out how the 3174 has been configured.
The keyboard maps are different according to the language being used. For U.S.
English, the keyboard maps map character graphics (Including space) as the actual
character graphic except for the following:
Key 3270 Code
[ 0
] !
1 ]
Note: DUP and FIELD MARK functions are not supported on ASCII terminals being
used as 3270 terminals, when the 3174 Is configured for Country Extended
Code Page (CECP).
The character translations are made on all ASCII terminal keyboard maps.
The keyboard maps use the following conventions:
• For key sequences that begin with ESC, press and release ESC and then press
the other key.
• For key sequences that begin with ALT, press and hold ALT while pressing the
other key.
• For the Control (CTRL) key:
— For ASCII terminals used as 3270 terminals: On key sequences that begin
with CTRL, press and hold CTRL while pressing the other key.
- For some 3270 terminals used as ASCII terminals, the CTRL key puts the
keyboard Into Control Mode which allows you to do one control function.
You do not have to hold the CTRL key while pressing the other key.
