These days, USB ports are easier to come by than serial ports.Has anyone heard of a way to control multiplecable boxes using one or more USB ports?You wouldn't need multiple serial ports if your cable boxes can be set for different IR codes, like satellite receivers. I don't know if they can or not, wouldn't hurt to ask your cable company. Instructions here: www.lircsetup.com <http://www.lircsetup.com>
And that is the difference between an IR *blaster* and an IR *transmitter*. A transmitter doesn't have the range/angle of effectiveness to control multiple devices, but a blaster does.
