Hi,
I think you got that backwards... you want ESC to be attention, and the
left-control key to be RESET. (Either that, or your version of Client
Access has very strange defaults! :) )
I'm doing this on some RedHat 6.2 boxes, and this is what I did....
fair warning: changing the keyboard mapping in this way doesn't only
change TN5250 sessions, but all console sessions will use the new
key mappings. (example: if you've mapped ESC to send Ctrl-A, it will
send Ctrl-A in all console sessions)
Here's what I did:
1) Make a copy of the default map, so that upgrades to tn5250 don't
wipe out your changes:
cd /usr/local/share/tn5250
cp us5250.map custom.map
2) Create a shell script to be run instead of the tn5250 binary, which
will load the keyboard map & term type automatically. On my system
I called it /usr/local/bin/tn5250-auto. Here's a sample:
#!/bin/sh
export TERM=5250
/bin/loadkeys /usr/local/share/tn5250/custom.map
echo -n "Type host to connect to: "
read CONNTO
/usr/local/bin/tn5250 ${CONNTO}
(Unfortunately, loadkeys requires root authority... so, you might
alternatively have loadkeys run at system startup, and omit it
from the script above...)
3) Make your keyboard mapping changes to the custom.map file. In mine,
I made ESC send Ctrl-A to the console, and Shift-ESC is still
escape so that the system is still usable for Linux. I mapped
the left control key to RESET, but left the right control key
alone. Also made mappings for back-tab, SysRq, set scroll lock to
help, and some other things. The following patch shows how I
did this:
