Just in case anyone is interested, one way I found to squeeze a 
few more bytes through your SLIP link is to set "tcp_extensions=NO" 
in your /etc/sysconfig file.  This disables the RFC1323 & RFC1644 
extensions, which are really intended for high speed links.
In fact, RFC1323 even suggests disabling it on slow links.

If you don't normally connect to other hosts that support RFC1323
and RFC1644 then you won't see any difference.  To determine if
a host you are connecting to supports RFC1323, try examining 
some traffic to/from that machine with "tcpdump".  If it indicates
that the "timestamp" option was present, then it is sending
the extra RFC1323 data.
