Parallel Port and Signal Generation

Just wondering if this could be done using QBasic and if so any info or supporting links would be greatly appreciated. I am trying to send out a varying pulse train for a small engine application. Any code or info on parallel ports and qbasic in general would be great.
Thanks,
Nick

If you are running QBasic in DOS or in windows 9x you can access the paralel port using OUT and INP from QBasic . If you are running XP or W2000 the OS's will not let you access the parallel port from DOS.
