First, use TCP port 7000+serial line number.  That avoids the telnet
option negoiation that Annex tries to do.  (Sends crap down the serial
line that can mess the minds of printers).

If you use port 515, then there is a protocol one-way involved.  If
you go straight to port 7000+, you get a bi-directional TCP stream - no
intervention by the Annex.
