Well, on a 425t, the only thing that EX CONFIG can do is set the clock
speed.  What's PNET E?  That sounds like what I might need...

Both the Cisco and Proteon route DDS.

I've done both, and the proper network is displayed.  A bldt, however,
shows no network.  Perhaps this again is related the the mysterious
"PNET E" you mentioned above.

29cf2 IS the ID for that ethernet spur.  It used to be on 29cf7, the main ATR.
