Yes it's an executable, so change it's permissions to 755
It wouldn't surprise me that most (if not all) of these free upload sites
use cookie tracking in form or another.
If CUPS is set up to use the LPT, then obviously it would not be recommended
to run LPTout on the same port.
This app can also be used to generate morse code if required.
Simply connect a small self-oscilating buzzer to one of the data pins via a
transistor as if you were using a relay.
So if you used say D0 (pin 2) for the morse, then by calling LPTout with a value of 1
then waiting a bit then 0, one can create the dits and dahs.
Rude messages made out of lights, mmmmmmm now there is an idea :-)
The app I created is only for simple tests/projects as it's quite limited by the
fact that the port address is hardcoded.
Once people have tested it and confirmed it's OK, I will expand on it and make
another version which allows any port address.
This will make it very versatile in that it can be used for the LPT, the serial port
even to "talk" to old ISA boards.
Since the "newer" version will be able to output to serial ports as well, one could
theoretically send characters to a VT-100 terminal.
