The Cat.5 (and Cat3,4,5e,6) cables are required to be standard colours.

There is a USOC (I think) standard for those flat cables.  If Cisco don't
follow it, they're buying cable from an odd place :-)
The two points I was making are (1) there is no standard for the colours of
the cable inside the hood, so noting which colours go to which pins isn't a
good way to specify it, and (2) there's no standard mapping of RJ45 pins to
DE9 pins either.
There's a good chance what you wrote would work, as it *appears* to be one
of the common arrangements, at least as far as the Tx and Rx lines are
concerned, but there's also a good chance it won't.
