Using the CLI Commands

Configure each terminal you specified in Step 3 to transmit 7-bit (rather than 8-bit)
control codes, to match the 7-bit codes in termcap and map3270.
At the same time, if your terminal has a keypad, you may want to configure the terminal to take
advantage of the map3270 keypad mappings. For example, if you are using the Model 5390
term_var of vt100 but the terminal has a numeric keypad (which an actual vt100 does not),
you can configure the terminal as VT200 7 bit, VT300 7bit, or VT400 7bit, which do support
keypads. The model you select depends on the capabilities of the terminal. Consult the
programmer's manual for the terminal being emulated. For example, if you are configuring a
VT100 to emulate a VT220, use the VT220 DEC Programmer's Reference Manual .
Use the following procedure to perform the two functions just described:
• Use the terminal's set-up utility or edit termcap to set the terminal's control codes to 7
bits and (optionally) to specify a terminal model number that supports a numeric keypad
To access the setup utility, press the appropriate key (typically labeled Setup). Then
choose the option that lets you select a value for the emulation mode parameter. (On
VT200s, VT300s, and VT400s, the option is labeled General, and the parameter you
select is Mode. For Mode, select the value VT400 7bit, VT300 7 bit, or VT200 7 bit.)
Instead of using the setup utility, you can set the emulation mode by editing the
termcap file.
C3-90
NOTE: During this process, tn3270 broadcasts for map3270 and term-
cap – even if the Model 5390 load_broadcast parameter is set to N. If
tn3270 follows the configured load-dump sequence but still cannot find
map3270 and termcap, it uses default, compiled versions of the files
that are built into the Model 5390 operational image. The default
map3270 file is shown in Table C3-36. The default termcap file contains
definitions for the following terminal types: VT100; WYSE Models 75
and 85; and IBM 3151 (For term_var, specify these as vt100, wy75,
wy85, and ibm3151. See Step 3.) Another Model 5390 server cannot act
as a boot-server for map3270 and termcap because a boot server only
returns files in its cache, and these two files are not cached.
NOTE: VT100 emulation mode always uses 7 bits, although not all
setup utilities indicate that it does.
