Regarding making sure your polling routine gets called at
least every 8 msecs: this is the whole problem...once your 80-col card
ROM gets into its scroll routine, it's hard to get control again.

Easier than interrupts is relocating the whole ROM code to RAM and
sticking calls to your polling routine in all the right places.

Regarding sending ^S to the host automagically: it's yucky,
it's awful, and it only works if you are *extremely* careful.
