Sounds like you're connecting your mac to a 68040 NeXT. The 040's use
an RS-423 serial port, and macs use ans RS-422 port. You will need a
different cable than the one you are using. Look at the zs man page
and set up your cable like the one for connecting a 030 to an 040. The
way I "made" the cable for connecting my slab and my gs, was I took a
"mac to modem" cable that goes from din-8 to din-25, and another null
modem cable that goes from din-8 to din-25, and just simply plugged
them together.

The actual problem is that the NeXT the rts line high constantly,
which, when using the printer cable, becomes connected to the Receive
data plus on the mac, causing it to null out everything that's sent.

For a while, I *was* using an Imagewriter II cable for transferring
files one way (no xmodem, cat ONLY).
