No. While each end might be able to communicate with the local modem in
command mode using different parameters, when they are in connected mode
the modems will not convert anything, just pass the exact format along.
So if one end is expecting 7E2 and the other is sending 8N1 there will
be a 50% chance that parity errors will be received.

Okay....
Now I'm thinking that there are really two phases / modes of
communications: 1) computer to modem commands, and 2) computer to
computer via modem connection data.
I think my previous statement applies to #2. I can see the value in
#1 being more liberal in what it recognizes and accepts.
But, I'd still be surprised if the following would work for #2.
[A]---(7E2)---{modem}==={modem}---(8N1)---[B]
Would A and B be able to transfer data between each other with
different (local) settings?
