Just a brief note -- rick@seismo tells me that SLIP is not the 
protocol described in RFC-914.  I haven't a copy of this RFC
so
I can't confirm this.

I have a question maybe you can help me on.

I need to specify a network protocol to use on top of IP running
on half-duplex links.  Clearly TCP is not useful, since it requires
positive acknowledgement.  The protocol I am looking for would involve
the following sorts of things: automatic retransmission of datagrams
a fixed number of times; occasional turnaround of the link under control
of the application; occasional "confirmation" of reception of a 
transmission, again probably at the application level.  I am curious if
anything like this has been done in the DDN community, and what the
experience was like.

Any thoughts on this are appreciated.
