Message lights.

Blinking lights have been used on computers for years. What they mean varies from system to system.Manuals for the systems will hae documention on what all the variations mean.  Even on the home computer they most all have an led that signifies whether the power is turned on to the machine

Maybe we could attach led to a local computer and then they are lit could mean one of ervera things depending on how ht e system is programmed.. You could start off with just two leds that you give you four possibilities.  Back then there were no computer screens to get information. 

You could even add even more light for more possibilities.The traditional way was to add led]s to the parallel port. Eight leds would give you 2^8 or 256 possibilities. Possibly more than you would ever need. First setup we did like this was for the Atari ST computer. The picture is using a 32 bit computer.

One could go a step further and instead of lights being on or off, a message could be sent in one form or another. A traditional choice might be to use something like the Morse code. You could use just use one led to get out the message. the message would be consecutive flashing of long and short lights. Since there is more than one version of the code yo would have to decide  ahead of time which version to use.

Once that is decide you sould have to decide how long for a dit (short flash( and a dah (long flash). or n alternative could be using two leds either one lamp lit for a dit and two lamps lit for a dah.

Though I might prefer the traditional method as it would lend it self to using. infrared signal between two systems. Then two systems could use the infrared as a backup if all other communication lines were not active.This is really true if your monitor fails.
