How do you access bytes from the old cartridge port while under OS9? I am
talking about the 8 or so K that the S&S pack, RS232 pack, and my custom
projects use.  All I need to know is how to read and write single bytes at a
time to the cartridge port in Basic-09.  I bet that it uses SYSCALL somehow,
but so far, I've had no luck.
