It appears my problem was that the serial port I
was using had XON/XOFF flow control. Once I disabled
that and set it for no flow control, I was able to
set slattach to 38400 and connect. I tried using 57600
but slattach wouldn't take that. Anyone know of a way
to get 3.2c version of slattach to use 57600?
Every so often, the connection "freezes" for about 5 seconds
then continues on...Is this normal for a slip connection?
or is that junk on the phone lines with renegotiation?
Thanks to all, especially Dr. Tom Blinn for some 4.0 man
pages that help put some things more into focus.

Subject: 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
