Re: Using Perl to make a hot-lead from any portby Moron (Curate) |

If you have a custom computer supplier (instead of the usual off-the-shelf trained monkeys) , they should be able to tell you which controller to get and it will have a manual that will tell you how to operate it from the PC. On second thoughts, because you are going to use a relay, if using unix or linux you just have to write lots of FFFF (hex) to the relevant device in /dev. More update: I also thoroughly agree with the replies that suggest isolating the port from the bell circuit. I had an idea for isolating with a rectifier although I am scratching that because it would only (literally) half work for a/c. -M Free your mind
