Rule 1

No information is better than wrong information.

Rule 2: See rule 1

P.S. In another life our people made some information displays. Only when the program was running along nicely would it send a series of pulses via the parallel port (remember them). A little C/D/R/C board hanging on the display module itself set the enable line. The C/D bit was so a stuck Data High wasn't a problem.
