<<Easy question time.  We bought a bunch of new pc's running win95 osr2.
Have a generic modem card installed.  When using reflections (any version
as far as I can tell) to dial into a clients hp3000, we can no longer use
the break key.  It seems to do nothing.

Is there a modem configuration that needs to be changed to allow this to
work?>>

I don't think it has anything to do with the modem. R1Win generates the
equivalent of the HP-terminal "Break" key using Ctrl+Break, and has for
as long as I've used it. As far as I know, a bare "Break" from R1Win
doesn't do anything. It's been so long since I used R7 that I don't
remember what it used for "Break".
