---------------------------------------------------
Object brief descriptions
Tdriver (and decendants) provide manipulation of the physical
LCD panel including backlight, typeface loading, etc.
Tdriver will provide default methods for tasks such as
text centering
scrolling
screen clearing
etc
TVirtualDriver could act as a frame buffer / virtual display.
This would allow several display objects to access the (virtual)
display in a single cycle and then the virtual driver can flush
the changes from the last display (delta display) in a single pass.
This provides a portable way to implement display objects
(like the heartbeat which only changes one character at a time)
but overlap a standard full screen display
Tcomms (and decendants) transmit and receive all data to and
from the communications interfaces. Tdriver and Tfeedback will
use these objects directly.
Tdisplay (and decendants) generate the actual display information
by manipulating the Tdriver object which has been given to it.
The Tdriver object should usually be a TVirtualDriver descendant.
Tremote (and decendants) create, keep track of and ultimately destroy
Tchannel objects. Each Tchannel can potentitally be an external
connection to a remote client. The remote client can generate
either complete screens in a similar style to a Tdisplay object with
Tchannel using a Tstub_dsp to generate the screen based on info
supplied to it or it can feed data into an existing Tdisplay object
(Tchannel will do this by setting Tdisplay properties).
Tconfig is responsible for parsing the command line and reading/re-reading
the contents of a configuration file.
Tfeedback (and its descendants) may communicate with a Tcomms object to
retrieve information from a keypad or other input device.
Tschedular is responsible for the overall co-ordination of everything.
Other notes:
I can't decide things like "should scroll stuff be down to Tdriver
or Tdisplay?".
Some sort of Thash would be a useful way of passing data from
sockets to display objects as well

1998-04-26: Scott
all: Implemented logical/physical drivers.. Whew!
main.c, mode.c, lcd.* have changed, and I've added text.* and
MtxOrb.* driver files...
New commandline option "-l driver" selects a driver.
1998-04-21: Scott
all: Lots of updates... (patches, etc)
Implemented a frame buffer, and custom characters...
Added lots of comments, and cleaned a few things...
Added a few function to lcd.c
1998-03-22: Scott
main.c: Should exit cleanly now, always... It sometimes wouldn't, if killed
by init at shutdown... (it would get stuck in a usleep for too
long, and then get killed instead of shutting down)
main.c: Changed timing method... Sequences now specify their length in
TIME_UNITs. A time unit is 1/8th of a second. This should make
blinking and other such things easy...
main.c: Removed command line options to specify timings... Why would the
user really need to change that anyway?
main.c: A few mode-feedback things are implemented: blinking, and backlight
on/off stuff...
mode.c: Xload_screen now sends feedback to toggle blinking for a high load,
or turn the backlight off for no load...
1998-03-13: Scott
Makefile: Installs man page in /usr/local/man/man1...
main.c: Now detects previously running lcdproc.
lock.?: New files for detecting another lcdproc...
Now detects an already-running process, and gets its pid. So far,
it just exits when this happens.
1998-02-28: Scott
Makefile: Now handles installation with "make install".
main.c: New command line stuff... (in man page) Also, default contrast is
140 now. Looks better from all angles, at least on my machine. :)
lcd.1: Man page. New.. :)
mode.c: Rearranged memory screen.. Shows Memory and Swap space separately,
with two graphs.
1998-02-24: Scott
mode.c: Rearranged memory screen. Worked around hbar bios bug. Added swap
info to this screen also, so get_mem_info is back to its former
state. (call it on an array)
mode.c: Fixed xload screen. It was displaying things one space to the left.
main.c: Changed command line style from "mode num_times delay_time" to
"mode total_time delay_time". Is this better or worse?
1998-02-22: Scott
main.c: Now handles SIGINT (Ctrl-C) and SIGTERM (kill) for a clean exit.
main.c: Default device now works. (device[] was getting overwritten by
argv[0], which would always be "lcd")
mode.c: Fixed CPU load meter. Decreased cpu buffer size back to 4.
mode.c: Made goodbye_screen() do something...
mode.c: Fixed am/pm on clock_screen(). Was previously displaying 12:xx:xxA
during the noon hour, instead of 12:xx:xxP.
1998-02-18: Scott
mode.c: Fixed crash on memory screen; commented out last two lines of
get_mem_info, which accessed a non-existent variable.
mode.c: Added "rep" parameter to all screen functions. Specifies how many times
that screen has been run. Using 0 will force screen clear/redraw, and
the time-based ones also use this to determine if colons should be drawn.
main.c: Implemented simple command-line parameters. Example:
lcd m 4 .5 /dev/cua1 x 1 2
uses /dev/cua1 for lcd, displaying memory info 4 times at .5 seconds each,
and the xload screen once for 2 seconds; then loops.
mode.c & lcd.c: created "NOLCD" preprocessor switch. When defined, lcd uses
text output (stdout) instead of the com port.
mode.c: Changed clock string generation to use "%02d" to achieve that
"02:37:06" look. (hint: printf can pad numbers with leading 0's)
main.c: Added minimal command-line help.

******************************************************************************
* Doubly Linked Lists! (some of my really old code, commented for this class)
* This code will handle "generic" Doubly-Linked Lists. These lists can be
* any type as long as they satisfy a few requirements:
* Your structure must start with two integer pointers:
* struct mystruct {
* int *next, *prev;
* ...
* };
* That's all, pretty much.
*
* Most of the functions take integer pointers. This means you will have to
* call them in one of the following ways:
* function((int *)&mystruct);
* function((int *)mystruct);
* function(&mystruct.next);
*
******************************************************************************
* If I'm not mistaken, this code should work regardless of your machine's
* integer size (16/32/64/etc... bit)
******************************************************************************
* Note that we have to do NULL checking to make sure we don't try to write
* to protected areas of memory if we reach the beginning/end of a list.
*
* We also do some circular-link checking to avoid infinite loops.
* These loops will work fine:
* a <-> b <-> c <-> a <-> b...
* a <-> b <-> c -> c -> c...
* This loop might make this code puke:
* a <-> b <-> c <-> d -> c d <- e <-> f <-> g

******************************************************************************
* Doubly Linked Lists!
* This code will handle "generic" Doubly-Linked Lists. These lists can be
* any type as long as they satisfy a few requirements:
* Your structure must start with two integer pointers:
* struct mystruct {
* int *next, *prev;
* ...
* };
* That's all, pretty much.
*
* Most of the functions take integer pointers. This means you will have to
* call them in one of the following ways:
* function((int *)&mystruct);
* function((int *)mystruct);
* function(&mystruct.next);
*
******************************************************************************
* If I'm not mistaken, this code should work regardless of your machine's
* integer size (16/32/64/etc... bit)
******************************************************************************
* Note that we have to do NULL checking to make sure we don't try to write
* to protected areas of memory if we reach the beginning/end of a list.
*
* We also do some circular-link checking to avoid infinite loops.
* These loops will work fine:
* a <-> b <-> c <-> a <-> b...
* a <-> b <-> c -> c -> c...
* This loop might make this code puke:
* a <-> b <-> c <-> d -> c d <- e <-> f <-> g

The first field is the text for the menu item.
The second field is a function to call when the item is picked.
The function should take no parameters, and return an int.
The return values are:
MENU_OK Normal return value. Menu will close.
MENU_CONT Menu will stay up after function returns.
The third field is the child menu to display when the item is picked.
Note that either the second or third field must be NULL. If both are
NULL, the item is considered to be just a label. (for example, a title)
It will be non-pickable if both are NULL.

0xFE Command prefix, followed by...
0x00 EOT. End of transmission, where applicicable.
0x01 Ping. Will respond with a "pong".
'k',x Send "keypad" input, character x (A-Z)

?,x Switch to new mode x immediately
?,xxxx Pause in current mode for x frames/seconds (0=infinite)
? Play -- continue mode cycle.
?,x,y,...,EOT
Send raw text to be displayed. x is style (raw, wrapped),
and y is num frames between lines displayed.
?,... Send MtxOrb-like control commands (bargraphs, etc)
... more to come later ...
**********************************************************************/
/*****************************************************************
LCDproc command line interface: (while running)
-command
Tells LCDproc to interpret stdin as raw commands to send through
the socket. Input must be formatted as above, in socket interface.
-function f
Runs LCDproc external function f, where f is one of the predefined
functions which can be assigned to keypad keys. (like NEXTMODE, etc)
-key x
Simulates keypad press of key 'x', where 'x' is (A-Z).
-print [time]
Prints stdin on LCD one line at a time, with no line-wrapping (raw),
with [time] frames between updates (lines).
-wrap [time]
Prints stdin as with "-print", but with line wrapping when possible.
-contrast xxx
Sets contrast to xxx (decimal)
-backlight [on/off]
Turns backlight [on/off/auto], or toggles it.
If [off], stays off.
If [on], stays on.
If [auto], LCDproc controls backlight based on load, etc...
-exit
-quit
Duh... :)
