pppd: 'tcsetattr: Invalid argument'

[Adam Bailey <adamb@lull.org>]

I'm trying to set up pppd using OpenBSD/mac68k. I've tried several
different configurations, all have the same result:

 Sep 13 22:00:27 aegis pppd[5834]: pppd 2.3.5 started by root, uid 0
 Sep 13 22:00:27 aegis pppd[5834]: tcsetattr: Invalid argument
 Sep 13 22:00:27 aegis pppd[5834]: tcsetattr: Invalid argument
 Sep 13 22:00:27 aegis pppd[5834]: tcsetattr: Invalid argument
 ^C

/var/log/messages doesn't show anything additional.


/etc/ppp/options:

 /dev/tty00
 115200
 debug
 nodetach
 modem
 crtscts
 defaultroute
 lock
 asyncmap 0
 205.243.156.212:198.147.221.1
 netmask 255.255.255.0
 deflate 12,12
 noauth
 connect '/usr/sbin/chat -v -f /etc/ppp/xnet.chat'

Yes, that is the right modem device. At least, it should be. I don't
think it's a chat script problem, since it doesn't even get that far.


uname -a:

 OpenBSD aegis 2.5 GENERICSBC#2 mac68k


I've found references to this problem on Deja.com, but the symptoms
always seemed to be slightly different. No one had any insights on
comp.unix.bsd.openbsd.misc or comp.protocols.ppp.

Any suggestions?

TIA!
