I have no way of testing it anymore because I only have one modem now, but
I remember Windows 95 being able to do something that NT couldn't. It's
possible that maybe it was a scenario like:
2 modems are connected using MP
The primary modem is disconnected (line noise or something) and only
the second channel is connected.
In WinNT the first channel cannot be redialed until the second one
In Win95, either channel can be disconnected and brought back up
without completely disconnecting/reconnecting.

Again, it's been a while since I've used MP on my home computer (NT4/95),
so I can't remember any specifics. I just remember that 95 could do
something with MP that NT couldn't. When we upgrade our Maxes to 6.0.0,
maybe I'll fiddle with MP again and try and figure out what it was that NT
lacked (aside from the ability to end a PPP session properly:
Ascend-Disconnect-Cause = 11 ("loss of carrier") instead of the normal 45)
