Plip now works.  Apparently I was giving the hostname of the computer I
was typing on, when asked for host name, and when I gave the same number
for ping, the computer I was on pinged itself, as you said.  Thanks!.

Instructions for use (that work):  type

ifconfig plip0 192.168.1.1 pointopoint 192.168.1.2  on either computer
type the same thing but switch the two numbers on the other computer

ping the second number that you typed on that computer and it should
transfer packets in a few ms.  If I give the first number, it transfers
packets in 0.0 ms (to itself).

When asked for the hostname give the second number that you typed on that 
computer, which is the hostname of the other computer.  If I give the 
first number, I get 'no connect' but it apparently still sends the file, 
like it says - to itself!

If you are the one who wrote the send script, you might want to dummy 
proof it some day when you have more time, so that it wont' send files to 
the sending computer when someone gives the wrong host name.  I have no 
idea how to do this since ping is working.

Either computer can send or receive, just type receive on one computer, 
send on the other, then send, to the hostname that was typed second on 
that computer.

Thanks for fixing my problem.  I was not looking forward to trying to 
configure an ftp server.

I did that and it gave some very cryptic info about things like PORT, 
which is why I asked.

What is a port?  (You don't have to answer if you are busy).
