Hmm.  pppd works just fine for me; it even hangs up the modem if I kill 
the ppd process.  And haven't yet had a problem restarting.  But I _am_ 
seeing lots of ser0: silo overflow errors, which just started since I've 
upgraded to -current.  Never used to get them on 1.0, even running the 
port at 57600, but with -current I get them frequently at 19200, 
continuously at 38400 or 57600, and occassionally when the port speed set 
as low as 14400.
