Command-line interpreter does not show prompt in comint

Content-Type: text/plain; charset="UTF-8"

I run a number of command-line interpreters under emacs (under Windows) and
this is my preferred interface but recently I have had trouble with a new
one (q) where the prompt provides information about being in debug mode or
not.  Unfortunately, emacs under comint (and eshell) does not display the
prompt.  When I had this problem with another interpreter, it was quickly
fixed in a subsequent release leading me to believe there is something that
can be done easily on the interpreter side of things to fix this issue.
However, I have no clue what this is.

Does anyone know what I can tell the interpreter writers they should look
into?  Is there something on the comint side I can do to get it to stop
swallowing the prompt?

Thanks,

Devon
