mset - retrieve ASCII to IBM 3270 keyboard map
Mset retrieves mapping information for the ASCII keyboard to IBM 3270 terminal special
functions. Normally, these mappings are found in /usr/share/misc/map3270 (see
map3270(5)). This information is used by the tn3270 command (see tn3270(1)).
Mset can be used store the mapping information in the process environment in order to
avoid scanning /usr/share/misc/map3270 each time tn3270 is invoked. To do this, place the
following command in your .login file:
set noglob; setenv MAP3270 "`mset`"; unset noglob
Mset first determines the user's terminal type from the environment variable TERM. Nor-
mally mset then uses the file /usr/share/misc/map3270 to find the keyboard mapping for
that terminal. However, if the environment variable MAP3270 exists and contains the entry
for the specified terminal, then that definition is used. If the value of MAP3270 begins
with a slash (`/') then it is assumed to be the full pathname of an alternate mapping file
and that file is searched first. In any case, if the mapping for the terminal is not
found in the environment, nor in an alternate map file, nor in the standard map file, then
the same search is performed for an entry for a terminal type of unknown. If that search
also fails, then a default mapping is used.
/usr/share/misc/map3270 keyboard mapping for known terminals
If the entry for the specific terminal exceeds 1024 bytes, csh(1) will fail to set the
environment variable. Mset should probably detect this case and output the path to the
map3270 file instead of the terminal entry.
