Assuming that you're using the curses version of TN5250, the font is
changed in cursesterm.c in a function called "curses_terminal_update."
Changing the font is actually the first thing that function does (if the
screen size has changed)

However, please try to find a way of doing this that's not
Linux-specific!!!   Keep in mind that we support TN5250 on many operating
systems, Linux is only one of them.

One possibility that jumps to mind would be having a shell script that
TN5250 could run whenever the window size changes -- that way, you could
have separate shell scripts for each OS.

Another thought would be to write your own TN5250 front end using svgalib.
(I'm assuming that svgalib has the capability of doing 132x27 somehow)


> Hmm.. is that a telnet thing and not a 5250 thing?

I don't understand this question.   Is what a telnet thing?


Also -- have you tried checking the keyboard codes in the GTK version of
TN5250?   I know that the keyboard handling is more "raw" in the GTK
version.  You'd still have to write code in gtk5250terminal.c to handle
each keycode, but it would be significantly easier than writing console
font support...

Just a thought...
