Is there a standard which defines the pin out functionality of the DB9
connector used for shielded twisted pair Token Ring? If yes, where do I
obtain it?

I understand that pins 1 and 9 are the receive pair and pins 5 and 6
are the transmit pairs.  However, varying on whose card you look at the
remaining pins are sometimes grounded, sometimes hooked to +5V, and
sometimes left hanging.

Hence, I need to know the standard. Advance thanx,
