a687a08b0b 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)

80edada6e9 DECCOLM 132 support (partial). 
I still don't support 132 mode but switching clears the screen, homes the cursor,
and clears any scrolling regions, so it's necessary for passing the vttest suite.

04113c4725 Rom 1 _InstallCDA call clobbers some direct page locations. 
This is fixed in ROM 3 (or via the TS patches if you boot GS/OS).
Workaround it by switching to DPAGE 0.

Also, allocate memory (since I originally thought that might be relevant).

1f7e3b3b4c to make life easier for emacs, backspace will send $7f instead of $08. 
command-backspace will send $08 (as will Control-H).
If you have an extended keyboard, delete will also send $08.
(mame uses delete to toggle keyboard mode so it's not yet tested).

60259531d5 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.

71993497ea $7f (delete) character is a null char. drop it (and $00) when checking the read queue. 2022-01-28 23:21:13 -05:00

acfe94a4c7 command keys: 
* command 1 - command 4 equivalent to PF1 - PF4
* command-delete = backspace (0x7f)
* command-return = linefeed (0x0a)

9cf52cb34e vttest fixes 
1. control-space should generate a null character
2. vt52 application mode keys were off.

Kelvin Sherlock
186d71de47 print the cancel character for ^X and ^Z. 
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.

1cc501e72a 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)

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.

2ae6964664 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. 2021-09-27 17:55:10 -04:00
