Redirecting the output is fairly simple, especially to the printer port; the
trouble is that it's still only 8 x 40.
I played with it years ago but can't find my notes right now; I'll keep
looking...

I do believe it has been done for the parallel port.

I did find a hack from the ROM2 manual, which POKES some values into RAM. The
problem is that it's super delicate, and if you turn the computer off while the
values are changed, you can't recover without a cold boot. (Don't ask how I
know that.)

I think you could achieve that with a little code and using the hook, yes. But
it isn't built in like ...say CP/M.
That would be a good thing to get sorted. Wonder if it exists?

I would like to have all of the computer's console output sent to the serial
port, and not just the screen. This would allow me to use a terminal or
terminal program to get an 80x25 output from the T102.
Has anybody seen a program like this? Is it possible to hook the $4B44 print
routine? Are there any good examples of talking to the serial port with
assembly language?
