It's not another serial interface. You need to do IrDA with TinyTP and
other protocols I don't recall the name of that are not implemented in
MacOS X (as far as I know). And even if you had these, the Newton doesn't
do MNP compression over IrDA, it does it only over serial and as far as I
know, NewTen is just a shell around UnixNPI which does MNP at the lowest
layer.
The only way to connect via IrDA and therefore bootstrap a Newton is to
use Thomas Tempelmann's DIL Tester on MacOS 9. Actually, some old sample
code of the DCL would do it as well (it's been a while since we didn't
compile any application for MacOS 9). I recall we did work out the
parameters of the IrDA communication toolbox tool with Thomas who even
used a DTS for it. If I recall properly, Laurent worked on that with us as
well.
Anyway, if you get IrDA working, I'd be glad to hear about the details so
I can add the layer to MacOS X. Using OpenTransport is not a solution as
OT on MacOS X is just a compatibility layer for TCP/IP and won't provide
serial, AppleTalk or IrDA unlike MacOS 9.
