I'm setting up a switch box so I can control eight SGI and Sun workstations from a single VT510 serial terminal and today I got a bunch of adapters that let me use regular RJ-45 network cable as the serial cable. They are repinnable so I want to set them up so I can use them for the task and I got eight conductors to work with. Now, for DB25 connections, which pins are important to the proper operation of the serial terminal?
EDIT: I'm finding pinouts for these adapters on google but I don't know if they are either a) to RS-232 stndards and b)what I want.
Apparently what I'm looking for falls under the Yost Serial Device Wiring Standard. About halfway down that page they mention DTE devices which I'm assuming I am using and that the listed pin to pin listing is correct and what I want. Is this correct and do I have to worry about this for what I'm planning on doing?:

Some DTE devices require the DSR (Data Set Ready) signal. This signal is usually provided by the DCE device. If you have a DTE device (such as a terminal) that requires the DSR signal, wire pins 20 and 6 (4 and 6 on a DB-9 connector) together. This way, the DTE device will receive the DSR signal from itself when it asserts the DTR signal.
