DECARM - auto repeat support. defaults to auto-repeat on.
...
n.b. - mame does not currently set the repeat bit in the keymod reg so it's not well tested.

based on testing, this applies to vt52 and vt100.
use the current x pos to choose between $56 and $57 (mouse text checkerboard)
so multiple characters look pretty.

buffer outgoing keystrokes
...
this also adds a hexdump in the CDA for the outgoing buffer
in local mode, "incoming" data is read from the outgoing buffer.
Currently data is (potentially) sent on each run of the main loop.
I thought about using the TX empty interrupt but it still needs to be
kicked off at some point (unlike incoming data)

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.
