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
