This is a patch to call.c.  This is against ax25-apps-0.0.8-rc2.
Only one file is changed, call.c

1.  Now supports UTF8 or IBM850 as the encoding style over AX25.
1a.  Attention was paid to make sure that wide characters worked
with East Asian fonts.
2.  Now the screen can be resized.
correctly.   The program no longer crashes when it is resized.
3.  Added a scrollback buffer.  Use the up and down arrow keys
or the page up/page down keys to scroll through history.
After the screen begins scrolling, press 'up arrow' to view
history.
4.  Many visual quirks have been fixed.

I tested with East-Asian fonts myself, and I tested with
international latin characters by dragging from charmap.
My US keyboard has no Alt-GR key, so I'm not sure
how to type them directly here.   I've been using
this myself for the last week or so, and I can't
find anything wrong, but, you know how that goes.

I did check on gnome-terminal, and xterm, and also konsole.
It seems to behave about the same on all of these, though,
the keyboard is mapped slightly different with the number
pad with some terminal emulators.  This was compiled on
a Fedora 12 system everything updated by me.

This version is now dependent on iconv and wide character
versions of ncurses, which I think should be everywhere these
days.
