from the responses i've received, (and thanks to all those who have
responded so quickly) i feel i need to clarify my question some more.
a few people asked if i ran ifconfig on the alpha to setup sl0.  yes,
i forgot to mention that i did.  if i do ifconfig sl0 on the alpha, i
get:
sl0: flags=10<POINTOPOINT>
     inet 128..alpha.address --> 128..pc.address netmask ffffff00  ipmtu 1500 
(and i have a corresponding entry on the pc.)
someone else wrote that
> in the network configuration manual (page 12-2) is a good example
> how to setup the sl0 interface!
i looked through it, but i want to set up a dial-up slip server, and
the examples all assume that the interface is permament.  i need to
have getty running on the tty01 in order to dial in, and then after
logging in, i want to run slattach.
a couple of people mentioned that since i am connecting at 38400, i
need to include the speed in the slattach command.  this may be the
root of my problem.  i did try putting the speed in the slattach
command, with no success.
i tried:  % /usr/sbin/slattach tty01 38400
but i got an error, "Not owner".
any idea why?  it may be that i am logged into this same tty01 line?
then i tried it as root: # /usr/sbin/slattach tty01 38400
but it disconnected me entirely.
if i don't put the 38400, it seems to work (i can escape out to my pc
correctly), but when i ping the alpha from the pc, it doesn't work.  i
get traffic on the modem in both directions, but no packets are
successfully received from the alpha.
thanks everyone for your help.
