WakeUpII is probably the most easy way to write your own blanker-module...1. It's written in Hisoft Power Basic. A very fast compiling basic, compatible with AmigaBasic.. (Almost everybody has got an AmigaBasic-manual somewhere at home)..
2. I have included functions that makes it very easy to use pref/default- variables that can be changed, using the pref-editor.. Like this:
Speed=PrefNum!("Speed",200)
After this line, you got a variable (Speed) containing 200 by default, and anybody can change it, just by double-clicking the blanker-modules icon... and the pref-editor will be loaded...
If you wan't a copy of WakeUpII, then take a look at my homepage, it is not there right now, but it will be in the future...
