I am trying to connect our Mac+ with the MicroVax computer.
On the Mac there is a modem plug with 8 pin connector; on the MicroVax
there is a 25 pin RS232 connector.
I have a cable from Mac which convert the 8 pin to DB9 connector.
However, I have trouble to connect the DB9 to our MicrVax computer.
In the Mac manual, it has the followings

pin 1   handshake
pin 2   handshake
pin 3   transmit -
pin 4   grd
pin 5   receive -
pin 6   transmit +
pin 7   no connection
pin 8   receive +

How should I connect this?  Since I don't read this newsgroup too often,
please mail the answer to me directly.
