Transmitted Keyboard Codes Transmitted codes are generated by computer keys and sent to the used host computer or software application. The next few pages describe computer capability to emulate codes generated by the VT/ANSI computer keyboard main keypad, editing keypad, auxiliary keypad, and top-row function keys. Codes are sent via Line Edit (block) mode or optimized Character mode selected through the keyboard function labeled MODE on the overlay. Line Edit (Block) Mode Line Edit (block) mode is a synchronous condition where the computer temporarily stores or "buffers" keys you press. It sends the cumulative data to the host computer when you press one of these terminating keys: • Enter • F6 through F20, PF1 through PF4 • CTRL+A through CTRL+Z • Forward Tab • Del (7F hexadecimal) • Backspace • Esc (hex 1B) For codes generated by the cursor control key, see "Cursor Keys" on page 76. For codes generated by the auxiliary keypad keys, see "Auxiliary Keypad" on page 76. When you press PF1, the following key will also be transmitted directly to the host computer. When scanning, the computer automatically enters Line Edit (block) mode for each individual scan. When it completes scanning, it returns to the mode it was set at before it started scanning. Character Mode Character mode (the default) is a condition where the computer sends, to the host computer, each key as you press it. You should place the computer into Character mode during these situations: • When the computer should immediately send information to the host computer. This operation is called "type-ahead." 74 Intermec Terminal Emulator (ITE) Programmer's Reference Manual
