Hey, I’ve written simple tool for my friend to control LPT port. Using this small program we can setup every pin on LPT port. This is beta version. How to use? ? it’s simple:
Options:
-v – verbose mode, print port information, where is 0/1.
-r – reset, set on every pin 0.
-s – set, set on every pin 1.
-d – use this option when you want to specify other address. For example -d 0×366.
-n – numeric, use integer values from 0 to 255 to setup port pins.
-2 – set D2 to 0.
+2 – set D2 to 1.

Examples:
# to see what is going on on port just use -v flag
./lptop -v
# set D4 to 0
./lptop -v -4
# set D4 to 1
./lptop -v +4
