1) The colour values are expressed as a percentage, not a 0-255 value.
2) Implement CSI ? 80 h/l to set/reset the sixel scrolling mode (defaults to
   set).
3) Document sixel commands.
4) Combine the extended set/reset mode commands in the documentation now
   that multiple modes can be set or reset with a single sequence.

CTerm (and therefore SyncTERM 1.0) required an extra two ignored garbage
bytes in the font data.

ESC ] 104 ESC \ will reset all palette entries.
ESC ] 104;X;Y... ESC \ will reset specified palette entries only.

ie: perl -e 'print "\e]104;1;2\e\\"'
Will reset palette entries 1 and 2.

ESC ] <string> ESC \

Where string is in the format:
rgb:R/G/B
And the values of R, G, and B are one to four hex digits.  For example:
"\e]4;1;rgb:0/0/a8" will reset the blue entry to the default value.

These basically never worked as documented.  Now they should, but they can't
save/restore the doorway mode setting since it's not set/cleared using
CSI ? h/l.  If that's really needed (you need to know the doorway state
regardless, so it's more likely that a query doorway command is needed if
anything) it can be added as a separate command.

1) Use a functional default (1) for P1.
2) Respond with an empty P2 parameter if nothing is set.
3) Only respond if there is a single parameter.  If there is more than one,
   it's not a request.

While we're here, clean up the formatting of cterm.txt.
Tabs for indentation, spaces for alignment, don't wrap with 80-column
displays using 8-char tabs (default with more).  The ECMA-048 reference
will always wrap however.

the DA response, so I added 2 new requests: CSI=1n and CSI=2n which query
a state report from the terminal (for font state or video/emu mode), the same
information returned in the DA in the previous rev, but in a format more in
line with the corresponding CSI? N h/l requests (no bit checking required).

slot numbers that have been successfully set by the server.

- first available loadable-font slot number (e.g. 43)
- result of previous "select font" request (0 = success)
- current video mode flags (e.g. high-intensity background)
- current emulation mode flags (e.g. cursor visible, doorway mode)

These are to aid the server (BBS) in making better use of advanced features,
namely alternative/loadable fonts and high-intensity background colors (aka iCE
colors). Being able to detect when these features are supported and working as
intended is vital in providing a smooth/automated BBS experience which is
automatically enhanced, when possible (supported by the client) and does not
interfere with legacy (non-enhanced client) users.
Even better would be a command that tells the server:
if the server were to attempt a request 'X', it would likely work.
Instead, we have to try request 'X' and then query the device attributes to
find out if it actually worked, which is better than nothing (or asking the
poor user to tell the BBS whether it worked or not).

the high intensity attribute can.  Using CTerm, this is controlled via the
CSI [ ? 34 h/l commands.

Also add CSI [ ? 35 h which disables blinking (reversed by CSI [ ? 35 l)

all along.  Make 41 and 42 the standard versions of the font since anyone
who has set up BBS controlled font-switching shouldn't be punished because
I messed up.  :-(

Add 8x8 and 8x14 Amiga fonts from http://www.trueschool.se/html/fonts.html
Clean up the music section of cterm.txt while I'm here.

Also add ESC [ ? XXX s and ESC [ ? XXX u to save/restore modes controlled
by h and l.

 38 - mO'sOul (Amiga)
 39 - MicroKnight (Amiga)
 40 - Topaz (Amiga)

As a reminder, to select a font, send the sequence "\e[0;40 D" where \e is
ESC and that space IS THERE.

Bright BG       CSI[?33h       CSI[?33l

ESC[?25h will show the cursor
ESC[?25l will hide the cursor

Update documentation to include erase character, DoorWay mode and cursor
control.

don't know the user supports ANSI Music.  For people with vt-style
terminals, ^N is a locking shift... which means lower-case characters will
be translated into graphic characters.

default note length for successive notes.  Used by KnK (and probobly others)

Thanks Ree.

Reformat to look properly with boith eight and four character tabstops.
