I'm afraid I don't know anything about a special "call-back process" for
Win95, but it's certinly doable (I have) with the normal scripting
functionality (which is included the standard distribution, but not
installed by default).

Well, the PM does send "Dialback...", but I don't know if that is any
help...

Yes, this is the main problem I encountered (real OS'es can of course
be, and typically are, set up to ignore DCD drop until the connection is
fully established) - the "simple" fix is of course to configure the
modem to keep DCD high regardless of presence of carrier on the line,
but then a "real" disconnect won't be noticed.
The other problem is that the script isn't run until W95 has dialed and
connected - you'd really want to get at it *before* the dial. Somewhere
in the twisty maze of click-and-config windows in W95 there is a place
to put "additional settings", but I haven't tried that.
Below is a W95 script that changes the modem config on the fly, setting
it to always keep DCD high before logging in, and then setting it back
again when the dialback is completed. On my modem (Powerbit a.k.a.
Intertex), this is done with &C0 and &C1 respectively, dunno if that is
standard - check your manual... It furthermore assumes that the script
in the PM location is just "atdt<phone#>\r" "CONNECT", i.e. no re-
authentication is done - if you need that, you'll have to hack it a bit.
