add command-L to toggle local/online
...
add command-Q to quit.
Since ROM 1 doesn't have _RemoveCDA in ROM, the control panel is only installed in ROM 3.
(TODO -- check at runtime in case launched from GS/OS)

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.
