Example: Configuring the French Onscreen Keyboard Input Method
The following example shows the configuration for configuring the French onscreen keyboard input method. The
onscreen keyboard input method is only applicable to T57W/T48U/T48S/T48G phones.
Customize the onscreen keyboard input method files “keyboard_lang.xml”, "keyboard_ime_francais.xml", "key-
board_ime_num.xml", "keyboard_layout_francais.xml", "keyboard_layout_2.xml" and place these files to the pro-
visioning server “http://192.168.10.25”.
Example
phone_setting.virtual_keyboard.enable = 1
gui_onscreen_keyboard.url = http://192.168.10.25/keyboard_lang.xml
gui_onscreen_keyboard.url = http://192.168.10.25/keyboard_ime_francais.xml
gui_onscreen_keyboard.url = http://192.168.10.25/keyboard_ime_num.xml
gui_onscreen_keyboard.url = http://192.168.10.25/keyboard_layout_francais.xml
gui_onscreen_keyboard.url = http://192.168.10.25/keyboard_layout_2.xml
After provisioning, you can use the French onscreen keyboard for entering information.
