IBM 3174 Reference Guide

Using Your 3270 Terminal as an IBM 3101
Using Your Keyboard
The main differences between the 3101 and the 3270 keyboards are in the ASCII
bracket and caret symbols. Referring to Appendix A, "Terminal Keyboard Maps,"
select the 3101 keyboard map that corresponds to the type of 3270 keyboard you
are using. For example, if you are using a 3278 keyboard, see the map called
"Using a 3270 Base Keyboard as an IBM 3101 Keyboard (702 = 1)" on page A-10. If
you are not sure what type of 3270 keyboard you have, see the keyboard diagrams
in Chapter 1, "Getting Started."
Typematic Keys
A typematic key is a key that repeats its function when you hold it down. All keys
that are typematic on your 3270 keyboard continue to be typematic, including keys
pressed with CTRL.
BREAK Function
The BREAK function (Field Mark or PA2 on the keyboard) produces a break signal
of 500 milliseconds. This function works differently depending upon the application
program that you are using. See your system administrator for more information.
Control Mode/Control Shift
Control functions are provided by a control key on keyboards where a control key
is available. Depending on the terminal type, the control key provides either a
Control Shift or Control Mode function. The Control Shift function allows you to
select multiple functions while the control key is pressed. The Control Mode
function allows you to enter only one control sequence. Both Control Shift and
Control Mode are indicated by a left-facing arrow displayed in the 01A.
On all keyboards, using the extension mode key or the Extended Select key
followed by
the control key invokes the Control Mode on/off function. See
Figure 1-2 on page 1-8 through Figure 1-4 on page 1-9 for the location of these
keys.
Understanding Your Status Line
The status line gives you indications of the operating state of your terminal.
Symbols, characters, and numbers appear in the status line to inform you of
conditions; for example, if your keyboard is locked, if it is in upper shift, or if the
system is busy. Refer to Table 2-9 on page 2-16 for information that can appear in
the status line, and what that information means.
Figure 2-2 gives you an example of a possible status line. The characters in the
example are explained at the bottom of the figure.
