Why do you need to do this? Pppd will just reconfigure the serial port to
its satisfaction when it comes up.
If you are just using the expect script to dial and negotiate a connection,
it would be much easier to use pppd's 'connect' option. One way to do this
is to create a file in /etc/ppp/peers/ just like the ones pppconfig makes
(naming it 'my_office', for example), but replace
connect "/usr/sbin/chat -v -f /etc/chatscripts/provider"
with
connect "/usr/bin/expect /etc/chatscripts/my_office"
Then you will be able to connect to your office with 'pon my_office'
and disconnect with 'poff'.

Do you really need to run as slow as 38400?

Which kills pppd, causing it to put the serial port back the way it found
it, i.e., as your stty command set it up.
