Well, I use Asterisk to call a Perl AGI script which drives a serial port DTR line high (using Device::SerialPort and Asterisk::AGI) for 20 seconds. The serial port line drives a transistor, which drives a large relay, which applies power to the (pre-existing) door solenoid. Fairly trivial if you know how, hard otherwise :-) - Mike -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
