Derek,

You will need an I/O controller to convert the serial command to a digital I/O signal. Devices are available from http://www.Opto22.com as well as many others to get you started..

HTH,

>Does anyone know a way with visual basic to trigger a motor to start running through a serial, lpt1, NIC or usb port. Is there some type of a command that can be used to trigger an electrical device to start running???? Please any help will be greatly appricated.
