- # Driver for Logic Controls PD-3000 Pole Display.
- # As with all pole display drivers, the control codes are contained in a hash
- # array called $pd_control.
- # THis pole display uses separate meanings for LF and CR. Both are included.
- # LF moves the cursor to the other line (same position), while CR moves the
- # cursor to the left-most spot (same line). Assume most PD's do this.
- # Most of this is simple ASCII, but what to make things clear.
- # This first part is straight from the manual.
- # Not including the bit about installing fonts.
- %pd_control = (
- 'mode_vscroll' => pack('C', 18),
- 'mode_normal' => pack('C', 17),
- 'bright_full' => pack('CC', 4, 0xFF),
- 'bright_high' => pack('CC', 4, 0x60),
- 'bright_med' => pack('CC', 4, 0x40),
- 'bright_low' => pack('CC', 4, 0x20),
- 'backspace' => pack('C', 8),
- 'htab' => pack('C', 9), # Functions like cursor movement
- 'lf' => pack('C', 0x0A),
- 'cr' => pack('C', 0x0D),
- 'digit_select' => pack('C', 0x10), # Pack followed by a number 0-39
- 'cursor_on' => pack('C', 0x13),
- 'cursor_off' => pack('C', 0x14),
- 'reset' => pack('C', 0x1F),
- 'scroll_message' => pack ('C', 0x05), # Followed by up to 45 chars.
- );
- # A few more useful control sequences:
- $pd_control{'new_line'} = $pd_control{'cr'}.$pd_control{'lf'};
