I'm trying to set up a port on an Annex II to handle SLIP.  I'm using the
"Two-Host Network" model described in the Annex Network Administrator's Guide,
using a V.32 modem at 9600 baud.

The pertinent data is:
	network number:		128.255
	subnet mask:		255.255.255.0
	Ethernet IP address:	128.255.57.6
	local SLIP address:	128.255.253.1
	remote SLIP address:	128.255.253.2
The Annex port configuration is attached below.

The problem is that the Annex doesn't seem to recognize the SLIP interface.
The manual says that the Annex should learn routes according to the
slip_remote_address and slip_subnet_mask on all SLIP ports.  However, the Annex
routing table doesn't include a route to the SLIP subnet, and all packets
addressed to that subnet get sent via the default route.

I've tried explicitly setting the routes via the Annex gateways file as
follows:
	net 128.255.253.0 gateway 128.255.253.1 metric 1 hardwired
	net 128.255.253.0 gateway 128.255.57.6  metric 2 hardwired
but the Annex complained that the gateway in the first entry is on an
unreachable network.  It accepts the second entry (intended for the other
Annexes) which mererly routes packets from the Annex to itself.

The receive light on the modem indicates that data is being received when the
other end of the SLIP link generates traffic, but the transmit light never goes
on.  The connection works fine in CLI mode, so the modem and async cables seem
to be fine.

Any helpful advice about this problem would be greatly appreciated.
