Where can I get some good documentation on SLIP? I have RFC1055, but it does
not state which of the actual protocols it uses (presumably because it can use
more than one). Now, I thought it used UDP in most implementations, and I'm 
trying to convince someone that he's not getting much, if any, error correction
on his SLIP connections, but he wants actual written proof. He thinks it's 
using TCP (as in "TCP/IP"), the same as Internet connections on Ethernet links.
I can't remember where I read (ages ago) that SLIP (generally) uses UDP; is 
there such a beast?

Our particular implementation is Rayan Zachariassen's streams SLIP for Suns. 
The closest thing I can find in the source code is that it includes the TCP
header definition from /usr/include/netinet/tcp.h if SLIP_FASTECHO is defined
(to give rlogin/telnet better response). But what about ftp? Does that use udp
instead, or does SLIP just use raw IP in this case? And what implications does
that have for error correction?

While enough personal testimonials would help, more formal-looking documents
would be better :-).

Thank you all.
