[comp.protocols.tcp-ip.ibmpc] CMU PCIP, SOS, and packet drivers: A Sad Story

fargo@iear.arts.rpi.edu (Irwin M. Fargo) (03/22/91)

I just recently got Clarkson's packet drivers and CUTCP running perfectly over
a SLIP line to the local netwrok here.

I'd like to try and get CMU's PCIP package running.  I found a package on
sun.soe.clarkson.edu:pub/ka9q/pcippkt.arc, which, I guessed from the name, was
PCIP for use with the packet drivers.  Now when I go in and customize
NETDEV.SYS, I find no information about setting up the packaet-driver inter-
face (ie. what interrupt number, etc.).  So I loaded NETDEV.SYS, loaded my
packet driver, SLIP8250.COM, and tried ping.  All I got back was an error
message entitled, "Packet driver not loaded".  Can someone tell me what I'm
doing wrong?

I also found on sun.soe.clarkson.edu, the file sos_pkt.exe, which claims to
be an NFS server for DOS that uses packet drivers.  There is no documentation
that came with it, and the documentation that came with pcip_sos.arc contain-
ed info on how to compile the package, but nothing else.  Can someone help
me here?

Thanks.

Sigh.  PCIP doesn't support SLIP (type 6) packet drivers.  There is no
reason in principle why it can't, it's just that the packet driver client
code to handle SLIP isn't there.  Perhaps you'd like to add it?  It should
be just a matter of grokking the existing slip and packet driver code, and
bashing them together.  It should be really easy because the packet driver
takes care of all the packetization.  It's just a matter of telling PCIP
that you've got a raw IP packet.
