Earlier, I had asked a question on how to write a byte to the parallel port. And Daan Vreeken was kind enough to point me to a litle c-source that uses /dev/io. Unfortunately, as I just found out, when I raise kern.securelevel to 2 (FreeBSD 4.7R), I can no longer open /dev/io for writing. :( That means I can no longer use this method; because there is no way I will allow my production server to run at kern.securelevel lower than 2. Which means I am back to square one. :( Sigh. Is there then no way to write a simple 0 or 1 to the parallel port, without compromizing the security of the server at large? Thanks, - Mark
