Ack!  Broadcast every non-local packet?  Have both routers respond
when both are up?  I think a far better plan would be, in BSD Unix
terms,

	route add default <my-ip-address> 0

So that every address is arp'ed for.  One or both routers will
reply, and one of the answers will go into the arp-cache.  I don't
know if or how you get the same effect in MSDOS.

The only trouble is that no arp layer I've seen yet will time
out an arp entry while it's being used frequently.  If the router
whose ethernet address you've cached goes down, and you don't
stop trying the same non-local host, the useless arp entry will
remain.
