I have rawkeyboard set to (auto) -- the default -- in my .dosemurc file.
Changing it to (1) or (0) doesn't seem to make much difference in how
soon CTRL+c crashes things.

With kystp in place, what setting are you using?

Thanks for the info, I'll give kystp a try and go back to CTRL+c.
You may have read this already online, but if not, there are other font
options for dosemu (though I usually use one of the default fonts).
If you have the Terminus fonts installed, you can try them out. They
come in a variety of sizes and codepages; the format for invoking them is

#$_X_font = "-xos4-terminus-medium-r-normal--16-160-72-72-c-80-ibm-cp850"
#$_X_font = "-xos4-terminus-bold-r-normal--16-160-72-72-c-80-ibm-cp850"
#$_X_font = "-xos4-terminus-medium-r-normal--20-200-72-72-c-100-ibm-cp850"
#$_X_font = "-xos4-terminus-bold-r-normal--20-200-72-72-c-100-ibm-cp850"
in the Fonts section of dosemu.conf or .dosemurc. (If a font's specified
in the configuration file but not available, Dosemu uses the default font.)
Generally, "-c-" (character cell) fonts work best if you don't use one
of the default Dosemu fonts; -p- (proportional) fonts don't work; a
couple -m- (monospaced) fonts work so-so (I've gotten some screen
artifacts at times). The command "xlsfonts -fn
"-*-*-*-*-*--0-0-*-*-m-0-*"|sort|uniq >scalable_fonts" will give you a
list of scalable monospace fonts that may be usable as screen fonts in
Dosemu. (You can check to see if xlsfonts is installed and will run by
trying "xlsfonts -h" first.) The output file ("scalable_fonts") will
have a seemingly endless listings of fonts, most involving variations in
codepage and face (roman, italics, reverse italic, etc.) A single
listing looks like:

-unknown-freemono-medium-r-normal--0-0-0-0-m-0-iso10646-1
You copy a listing to .dosemurc and add an appropriate size to the font
specifications (modify the -0-'s in "--0-0-0-0-m-0-"); some sizes will
produce screen artifacts. In my experience it wasn't worth trying out
any but the "-r-normal-" (the "-r-" is the critical part) fonts.
Examples of some of my experimental modifications:
#$_X_font = "-monotype-andale
mono-bold-r-normal--0-0-100-100-m-0-iso10646-1"
#$_X_font = "-monotype-andale
mono-medium-r-normal--0-0-120-140-m-0-iso10646-1"
#$_X_font = "-monotype-courier
new-semilight-r-normal--0-140-100-80-m-70-iso10646-1"
#$_X_font = "-unknown-freemono-medium-r-normal--0-180-0-0-m-0-iso10646-1"
