OK, I apologize for being a little bit too cryptic.
CTB (Communication Toolbox) is some kind of library available on
MacOS. It provides standard signals. It's just that DIL Tester relies
on them to do IrDA, and since it's a MacOS library, it's not
available on Windows and therefore DIL Tester cannot do IrDA on
Windows.
On the contrary to what John Anderson seems to think, you cannot just
redirect the serial signal to an IrDA device (IrComm or SIR) for the
Newton to recognize it.
As you realized, NCU and DIL Tester don't do pure serial but MNP over
serial and the Newton doesn't expect the IrDA stream to be MNP
compressed (which isn't really a compression, rather parity bytes).
But even if you could have an uncompressed stream, it wouldn't be
enough. You need some handshake with the Newton.
Sorry to say that, there is no way (with Apple's DILs) without
writing your own communication layer to do IrDA on anything but MacOS.
