Admittedly, I know nothing about the inner workings of iOSTransport...

There is a TSerialChipVoyager implementation in the REX, but I haven’t looked at it carefully. I suspect it might just be an implementation that No-ops the serial port, as when you try to access the serial port in Einstein nothing happens. Might just need some patched functions on the emulator side, I’m not sure.
Allright! The missing Einstein stuff is in
void TNativePrimitives::ExecuteSerialDriverNative( KUInt32 inInstruction )
which lives in src/TNativePrimitives.cp
The binary stubs in Drivers/TSerialChipVoyager.cp actually seem to be in place, but nothing in ExecuteSerialDriverNative is called. Instead we get the "missing resources" error when we try to open a serial port. So this may be a missing hardware register or whatever. Gosh, I am so mad at myself!
I used to know this. Age!
