I agree that this would be useful.

I prefer something like:
[generic]
Driver=atgen
Device=/dev/ttyS0
Baud=115200
Read=on
Local=on

We can even capitalize the values in gattty if it makes things easier.

Everything is a driver, in this case we mean the modem driver.  These are also 
generally always plugins of the same name which leads to confusion.
