The 3-port card is a DCE device, unlike the tty01/02 ports that are DTE.
A standard null modem should work.  I have heard reports that the 3-port
cards did not support modems well before XENIX 3.2, but I've never used
a modem on tty04-9.  Two 6000's with a null modem between them run just
fine at 9600 if tty01 or tty02 are used on both machines. I routinely
download at 9600 using ZMODEM from tty04 and tty08 without a dropped
character.

If you have a II/16/16a you will also need to check your Z80 CPU card.
Rev C with fixes is supposed to work, but we never got anything but
Rev D to work (works fine without the 3-port card).

Finally, does anyone know where the MMU and the 3.2 development system
now reside?  Our local manager was told that both products were still
alive, but when?
