Description

These are older versions of the Backlight driver. Please use Version 2.0 or later, if possible! This driver lets you switch a backlight via hotkey. The backlight control line must be connected to a specific I/O pin of the palmtop's CPU. v1.1 is slightly modified by John to support specific EL panels (automatic screen inversion. for example).

How to install it

What to send to the palmtop saves 9.8 KB

These are the files you need. You can send them from the package contents below.

  • backlite.com → A:\SOFT programa de DOS 924 B
  • backlite.com → A:\SOFT programa de DOS 869 B

No need to put backlite.asm: they are manuals, source code or supporting material. Read them here and save 9.8 KB on a 1 MB disk.

Steps
  1. Copy backlite.com, backlite.com to A:\SOFT. They are DOS programs: run them from the DOS icon, or add A:\SOFT to the PATH in C:\AUTOEXEC.BAT to call them by name.

Derived from the package contents and the 200LX conventions. It installs to A: on purpose: C: is a RAM disk and every byte there is memory taken from the system.

Send to my palmtop

The palmtop must be waiting before you press the button, or the transfer will fail. It is the palmtop that announces it is ready, not the other way round.
