John....
Oh yeah, tons and tons of the DB9 to DB25 connectors using the flat
silk type cablings (light blue and black) or standard RJ45.... I don't
think the cross over cables for CAT5 would apply like a null-modem cable
though, you'd need to check the wiring in the hoods.... the cross overs
reverse cat5 like this:
Straight Xover
1 Org/Wht Grn/Wht
2 Orange Green
3 Grn/Wht Org/Wht
4 Blue Blue
5 Blue/Wht Blue/Wht
6 Green Orange
7 Brown/Wht Brown/Wht
8 Brown Brown
So in the x-over cable what you are doing is switching 1&2 for 3&6 and
vice-versa

The great thing about the
console ports on most devices is that they use standard straight run CAT5
cables so you don't have to make up a custom one.
And if you're out junk hunting or raiding someone else's junk
closet, you might find a pile of the 9-pin and 25-pin to RJ-45
adapters that Cisco includes when you buy a router with a
console port. I hadn't thought about it that way, but is
this a handy source of alternatives to long serial cables?
If I use a cross-over cable, it is wired like a null modem?
