at 2.6mhz, 9600baud, I was experiencing lost characters during line scroll or screen clear. To compensate, replace modem polling with asynchronous/interrupt-based code. Up to 256 bytes of modem data can be buffered.
...
Also, enable modem, vt100 as default
Also, erase screen before switching to 80-column mode to prevent unsightly flashes.

clobbering the screen holes is bad. The slot 4 mouse code stores config data in the screen holes. on ROM 1, ESC#8 (fill screen with 'E') would cause the slot 4 mouse to enable ADB mouse interrupts, which causes ProDOS to eventually error out with 255 unclaimed interrupts.

to handle DECAWM mode, bit 7 of x ($80 + 79) indicates a wrap is imminent, as opposed to just being in column 79. backspace, etc will drop back to column 78 (based on testing).
