Hi there,

As the subject line says, the version of SLIP for 386/ix authored by John 
Ioannidis works.  We tried it here to link a 386 to a Sun 3, and after some 
fooling around with the termio settings we managed to make it work.  However, 
there is something wrong with the way it interacts with the rest of the TCP/IP 
stuff (at least in version 1.1 which is what I have).  For one, my mountalld 
fails to mount any remote file systems, and I'm getting the following msgs 
just after the booting processes is completed:

Can not register service: RPC: Timed out
unable to register (SMC_PROG, SM_VERS, UDP).

Can not register service: RPC: Timed out
Assertion failed: line 420 of pcnfsd.c: "svc_register (TransportHandle,
PCNFSDPROG, PCNFSDVERS, Disptach, IPPROTO_UDP) != NULL

My impression is that I must tell UDP not to try to use this interface, and 
I'm obviously not succeeding in doing this. I have included a little piece of 
code, in the section for minor device 0 of the slip_open routine of the driver, 
to mark the interface as a point-to-point connection.  A similar segment in the 
section for minor device 1 checks for the right flags.  However, when minor 
device 1 is opened the flag settings appear unchanged.  Also, netstat -r or -i 
does not show the interface as point-to-point.  Any ideas?.  Cheers,

	-- Jose
