Here the situation.  I have 4 Computer Peripherals 2400/MNP5 modems for
dial-in purposes (plug: modems have been working like champs, I could not
be happier).  

I initally did not have the MNP5 features enabled since I was never connecting
that way, but I finally decided to set it up.  When I finally tried a MNP5
to MNP5 connection I was disappointed at the little to no speed increase.
It took me a couple of minutes to realize that if my Sparc -> modem serial
connection was 2400 baud, there was nothing a MNP5 modem connection could
do to overcome this restriction.  All I had to do is up my Sparc -> modem
serial speed to 9600 and voila: close to double speeds with the MNP5.  Very
nice!!

Now the problem: users logging into my system at *normal* 2400 baud (1200 and
300 also) have their environment set to 9600 baud.  The modem handles the
speed mismatch so there is not a problem there, but anything that uses
a termcap-like database (gnu-emacs for example) thinks you are on a 9600 baud
line and sends 4 times the number of padding NULLs.

I have tried to set my modems to auto-baud on the Sparc serial connection
in parallel with the modem connection but I am finding that MNP5 connections
get set to 2400 baud.  Back where I started with no speed increase.

Am I missing something?  Do I have any bad assumptions/information here?

thanks for any help,
