PPP problem, ppp8?!?

[Max Lock <max@tele2.co.uk>]

 Hi folks,

 I'm trying to configure pppd version 2.3.11-1.4 as per release 2.2-r0.
I call pppd using the command `pppd -detach /dev/ttyS1 9600' my config
files look like the following

/etc/ppp/options:

 10.1.60.1:10.1.60.2
 asyncmap 00000000
 auth
 lock
 name 1313
 debug

/etc/ppp/pap-secrets:

 1313 * 1313 *

/etc/ppp/ip-up:

 #!/bin/sh
/sbin/route add -net 10.1.0.0 10.1.60.2


/var/log/messages:

pppd 2.3.11 started by root, UID 0
Using interface ppp8                   <--- shouldn't this be ppp0
Connect: ppp8 <--> /dev/ttyS1
modprobe: Can't locate module ppp8
ioctl(SIOCSIFMTU): No such device(19)
tcflush failed: Input/output error
Exit.
  
 Has anyone hit this problem before? my ppp support is compiled into
kernel 2.2.17 as a module.

 -Cheers Max
