I presume I was using PPP since the others were not running.
When telnet worked I was able to telnet to 192.168.1.1.  I don't think I 
installed the ethernet driver first.  How did my computers know that was 
the number of the one I was telnetting to?

How would I telnet over an ethernet connection?  I experimented and got 
nowhere (loading the ethernet drivers then in.telnetd then trying to 
telnet with kermit).  Perhaps this is due to my hardware problem.

I am getting thoroughly confused.  ppp, ethernet, agetty.  I am not sure 
what cable is involved when.  Is ppp using the nullmodem cable?

I don't have that file.  It worked anyway when I telnetted.

So I could telnet via ethernet?

I set up ethernet and tried to telnet to 192.168.1.1
Unable to connect to remote host:  Connection refused.

When it did work was I connected via ethernet or serial cable?
I had telnetd running at the time.
