  10. Keyboard Mapping How-to configure the keyboard mapping? On-line help In the VT configuration TIP! -> In the configuration file The keys are grouped by terminal model (ANSI, VT52, VT100) then by function type (FN, Shift + FN, Cursor) : FunctionKey Terminal model SEQUENCE sent to Host [VT_FNKEYS_ANSI] Function keys for an ANSI emulation. [VT_SFNKEYS_ANSI] Shift + Function keys for an ANSI emulation. [VT_CURKEYS_ANSI] Movement cursor keys for an ANSI emulation. [VT_CURKEYSAPP_ANSI] Movement cursor keys for an ANSI emulation in “application” mode. The sequence differs following the emulated terminal (TTypePreferred).

  11. Keyboard Mapping A keystroke that is not in any group On-line help On-line forum You need to: Identify the 'scancode‘ of the key or keystroke to be mapped to an escape sequence. • Configuration (VT file) • [VT_SCANCODES]Allows to map any scan code to any sequence (regardless the selected terminal type). • One scan code (key) • One sequence to send to Host • Example: • To map needed special characters that are not present in the PDA keyboard. Press “ESC” to perform a “tab” TIP! -> Identify the scan code: In the “Keyboard Test” dialog on the PDA it is possible to check the scan code generated by any key. Configuration > Keyboard Test On-line help

  12. Touch screen actions

  13. Touch screen actions With the touch screen, the stylus or the fingers, it is possible to perform actions Available features Display scroll Scroll the display in the virtual screen by moving the stylus.
