Lightnix is a open source serial/parallel port holiday flasher driver for windows. You can see its full capability by opening winlight.exe at the command prompt.
Examples
Flashing lights from serial port com1
Winlight.exe flash=100 com=\\.\COM1
The number in blue is the slowness speed of the flash in milliseconds and \\.\com1 is the com port path. This way can only flash up to 2 strains of lights at once.
