SLIP speed negotiation

I am running 3.2c on an Alpha 2100, I am trying to setup
a SLIP connection to a linux system running Slackware 2.0.30.

I am using 2 33.6k modems over the phone lines (modem <-> modem)
The setup works fine (except a bit slow & choppy) at 19200.

The problem I am having is how to up the speed, since if conditions
are ideal the modem connection speed can be 33.6k and with
compression (if it can be used?) can seem a lot faster. (so they say).

Right now, I'm using:

slattach /dev/tty01 19200


Questions:
1. how do I find out what kind of UART the alpha has? should it be
   able to handle a connection better than 19200 to a 33.6k modem?
   (it's a 4/275).

2. What baud rate would be best to use in the slattach to get the
   most out of my modem?

3. The linux end has a 16450 Uart chip. Could this chip be preventing
   me from making a successfull connection at higher speeds.


This is one project I will be happy to get out of my hair......

Thanks
