Anyone have any ideas why MacTerminal will not dial
through my US Robotics Auto Dial 212A when set to
7 data bits and even parity? I've found that I can
use 8 data bits and no parity just fine and then
switch the settings to 7/even after I've connected.

The USR modem is Hayes "compatible". MacTerminal
is version .5.

Another thing I had to do was jumper pins 5 and 20
on the 25-pin connector to the modem to hold DTR
high. As I'm not an rs232-c expert, I have no idea
why this must be done.

The pins I'm using are:

Mac Modem
5 2
9 3
1 7
7 20 (with 5 tied to 20)

Any answers or speculation?
