I really doubt that's it, since a) it works fine from Linux, whenever
it gets carrier, and b) sometimes we do start to negotiate, but it's
universally unreliable, and I don't think we've yet completely
negotiated IPCP (though we have started to).  A look at the modem
lights seems to indicate that we do get data back at the same time as
we send it, but the pppd logs don't corroborate that.

...a bit later...

Enabling crtscts seemed to let us connect, but here's some netstat
output from the PPP interface while trying to look at some web pages to
which we've gotten good throughput through the linux box:
   input    (ppp0)    output            input   (Total)    output

and then the NetBSD box froze up, and it stopped responding to pings or
keyboard input, and I had to hard-reboot it.  No messages in /var/log to
clue me in or anything.

I expect I'll have to do a fair bit more digging..
