I've been meaning to send this out for some time.

My 370 has a DB9 on the back with a non-standard (well, nonstandard
to modern PCs with DB9s) pinout.  I got a serial cable with my 370
to connect it to a standard DB25.

Since I use serial console on all my machines I worked out the pinout
to use a fairly standard DB9 modtap with the normal cisco pinout
modtaps or a cisco 2511 terminal/console server ... thought it might
be useful in case anyone else uses modtaps instead of traditional
serial cables;

RJ45:
8 white/grey           []
7 brown              [    ]
6 yellow             [||||]
5 green              1    8
4 red       viewed from connector end
3 black
2 orange
1 blue

CONNECTOR:      RJ45-9D
