OK. Been experimenting with different software.

Mk.558 's guide has been very useful.

Also have been toying with Bbraun's Serial Disk viewtopic.php?f=29&t=19729

No success on any front yet.

I have tried this both with the SE and the Plus.

I thought my home made cable may just not work, but I get the same result using one I spent a little-too-much-for as well.

Here's what I've tried so far.

System 7.01

MacPPP v2.0.1

MacTCP v2.0.6

I don't have Ethernet in the chooser?

So on that front I was a bit confused.

I also tried connecting ZTerm to Hyperterminal on a windows machine

ZTerm to CAT on linux.

No real response on either of those also.
