  • Page 21: Keypad Operation

    TECHTERM TECHNICAL REFERENCE MANUAL Keypad Operation The standard 30 position and 45 position keypads consist of uppercase letters, digits 0 through 9, punctuation marks, symbols, function keys and keys for Escape (ESC), Space (SPACE), Backspace (BACKSP/BKSP), Control (CTRL), Shift (SHIFT) and Enter (ENTER). You can program the SHIFT key to operate in normal or locked mode.

  • Page 22: Operating Modes

    Whenever a character appears in the last position of the top three rows, the cursor will move to the leftmost position on the next row. Whenever a character appears in the last position on the bottom row, the terminal will temporarily hide the cursor. After scrolling the screen up one row, the TechTerm will display the next character in the first position on a new bottom row followed by the cursor.
