    As we discussed on the phone, the problems you were having are due
to a misconfigured DEUNA.  The second DEUNA on your machine should
appear as "XEB0", not "XMC0".  The "XM" devices are the result of VMS
loading the wrong driver because the DEUNA is at the wrong Unibus CSR
for the AUTOCONFIGURE.

    To add the second DEUNA to your configuration once you have it
configured correctly:

$ multinet configure
MultiNet Network Configuration Utility 2.1(43)
[Reading in MAXIMUM configuration from MULTINET:MULTINET.EXE]
[Reading in configuration from MULTINET:NETWORK_DEVICES.CONFIGURATION]
NET-CONFIG>add se1
[Adding new configuration entry for device "se1"]
VAX/VMS Device [XEA0] xeb0
BSD Trailer encapsulation: [NEGOTIATED] disabled
IP Address: [NONE] 128.165.0.1
IP SubNet Mask: [NONE] 255.255.248.0
Non-Standard IP Broadcast Address: [NONE]
CHAOS Address: [NONE]
PUP Address: [NONE]
[se1 (Shared VAX/VMS Ethernet): Csr=NONE, Flags=%X0]
NET-CONFIG>exit

    Note that your default gateway (as set with the SET DEFAULT-ROUTE
command in NET-CONFIG) won't be affected by adding the second
interface, and MultiNet (like any 4.3bsd-tahoe networking) will
automatically route between the two interfaces.
