k, i read the section on understanding bug reporting. thanks. i see
now that my explaination was a tad vague.

the program that i run with comin-run does of course accept signals,
it's comint-run that doesn't send any to the program, eg

        M-x comint-run RET swi RET

to start swi prolog (yes this example only works if you got swi
installed and in your PATH maybe a new ispell could do as well???),
then i want to do

        C-c C-c

that is, comint-interrupt-subjob to send the swi programme an INT
signal. It does not work on emacs version 21.1.1 or 20.7 running on
solaris 9, though on a solaris 8 box i does using the same emacs
binaries.

in my example above, how do i know that it is not swi that rejects
signals? well i can send it a signal from any tty on the same system
with something like

        kill -INT swi-pid

which will work.

actually none of the comint-signals seem to work.

i got an answer from usenet saying that they have had the same problem
with hpux 11... though in this i will not speculate.

i think this was a tad more elaborative don't you think so?

uhm, i can do prolog... i am terrible at c :)
