Thanks for that. One thing still confuses me though. If I do this on
the command line for the examples/test program, then everything works. If I call

el_set (el, EL_SETTY, "-d", "intr=^@", NULL);

immediately after the EL_SIGNAL command then this doesn't work? Even more
curiously, in my application if I call el_set as above it doesn't work until I
have entered at least one carriage return, and then it does start working from
that point on. This suggests that the command I am calling in C is doing the
right thing, but somehow I must refresh the editline object to get the updated
tty. My application somehow does that after a carriage return has been
processed, but examples/test never does?

thanks,

dan.
