The CwLnx Driver
This section talks about using LCDproc with the serial / USB LCDs CW12232, CW12832 and CW1602 by CwLinux.

Features
The CwLinux CW12232 LCDs are graphical LCDs with 122 x 32 dots that also have a text mode with 20 x 4 characters, the CW12832 are graphical displays with 128 x 32 dots and a 21 x 4 character text mode, the CW1602 LCDs are character LCDs that are 16 characters wide and 2 lines high.
The modules can be ordered bare or as part of a kit mounted on brackets that fit in half-height 5.25" (CW12232 and CW1608) or 3,5" (CW12832) drive bays. The mounting brackets optionally feature a 6 button keypad that makes use of the keypad connector on the display modules.
The kits allow to programmatically switch on/off their backlight. Newer revisions of the kits also have programmable brighness as well as 4 general purpose IO ports.
The displays come in 2 variants that differ how they communicate with the host: The serial modules are connected to the PC using a serial RS232 connection getting operating power using the standard floppy drive power connector, while the USB modules only require an USB connection.

Configuration in LCDd.conf

[CwLnx]
Model = { 12232 | 12832 | 1602 } 	 Select the LCD model [default: 12232; legal: 12232, 12832, 1602]
Device = DEVICE 	 Select the output device to use [default: /dev/lcd] May be serial device or USB device in serial emulation mode.
Size = 	 Select the LCD size [default: depending on model: 12232: 20x4, 12832: 21x4] 1602: 16x2]
Speed = { 9600 | 19200 } 	 Set the the baud rate for communication with the LCD. If not given, the default is 19200.
Reboot = 	 Reinitialize the LCD's BIOS [default: no; legal: yes, no] normally you shouldn't need this
Keypad = 	 Tells if you have a keypad connected. Keypad layout is currently not configurable from the config file.
KeyMap_A = KEY 	 KeyMap_B = KEY 	 KeyMap_C = KEY 	 KeyMap_D = KEY 	 KeyMap_E = KEY 	 KeyMap_F = KEY 	 If you have a non standard keypad you can associate any keystrings to keys. There are 6 input key in the CwLnx hardware that generate characters from 'A' to 'F'. Legal values for KEY are Up, Down, Left, Right, Enter and Escape.
The following is the built-in default mapping hardcoded in the driver.
KeyMap_A	Up
KeyMap_B	Down
KeyMap_C	Left
KeyMap_D	Right
KeyMap_E	Enter
KeyMap_F	Escape
You may leave it unchanged if you have a standard keypad. You can change it if you want to report other keystrings or have a non standard keypad.
keypad_test_mode = 	 keypad_test_mode permit to test keypad assignment Default value is no
