[pups] 2.11BSD networking on simh

[luvisi@andru.sonoma.edu (Andru Luvisi)]

I finally tracked it down with strace.  The send() function was
complaining about not being connected.

By changing it to a sendto and providing some hard coded data I was able
to make it work.  Obviously this is not the "correct" solution, but it
illustrates the problem.

Here's the patch:
