I am trying to connect a micro-VAX 2000 to a PC-Clone. I would like to
use the serial ports and connect them directly using twisted-pairs.
The computers are about 3000' apart. Can any kind soul please tell me:

- which pins on each side need to be connected, 

- what the maximum distance / speed I could expect with such a
  connection and 22/24 gauge twisted telephone wires?

- finally, does anyone know what kind of connectors I need for each end?
  Part of the problem is that I've never seen the uVAX so I don't know
  what kind of connector it takes. (Also where can I get such
  connectors in a configuration that would allow me to custom build the
  null-modem cable?) 

Any and all help is appreciated...
