Kelvin Sherlock 77ec62a091 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.

vt100.screen.S

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.
