Re: New User Requires Help With Keyboard Re-mapping] -- LINUX5250

Thank you for your reply, but I just can seem to get it working properly!

I using Version 0.16.3 of tn5250 on Linux Mandrake 8.1 with KDE.

I connecting to "gec400", which is defined in the hosts file as 198.25.23.3

I created a program shortcut on the desktop:
� Command: �/usr/local/bin/tn5250
� Run in Terminal: Yes
� � �Terminal Options: gec400

This works fine in running the tn5250 emulator.

I tried Command: /usr/local/share/bin/xt5250, but that did not work, it does
not connect at all ???? How can I run this script? (As it is recommended in
the HOWTO manual.) (It appears that the mapping does not work, because I
cannot run the xt5250 script.)

If I rather use tn5250 (as I am using now) what file (and how) must I change
to include the keyboard mapping? If it is in ~\.tn5250rc then what is the
format of the file, seeing that is is:
� gec400 {
� � � host = 198.25.23.3
� }

I modified the XTerm file in /usr/local/share/tn5250/ for the keys I wanted
to map, but it does not appear if it works:
Key pad plus as Field Plus: � <Key>KP_Add: string("\030") \n\
� � It appears to be working - but only sometimes? Sometimes it displays a
"+" in stead of advancing to the next line / page.
Key pad enter as Field Plus: � <Key>KP_Enter: string("\030") \n\
� �This does not work!
Page Down (not key pad page down) as New Line: � <Key>KP_Enter:
string("\033\012") \n\
Left Control as Reset (default): � <Key>Control_L: string("\022") \n\
� �(This does NOT work. If I press Cntr L, it works (evern if I use the left
control key, buy if I press ONLY the Control Left is does NOTHING!)
Backspace does not work at all! When I press it, it displays a blank.

Where do you find a list of the keys on the keyboard descriptions, e.g.
KP_Left, Cotnrol_L, etc.


Thank you for your help so far.
