The problem with these adaptors is they are ‘virtual ports’ and they get assigned a random COM port name such as COM7. So I have to use a USB to Serial adaptor to talk to the projector. They are both linked by a KVM extender which squeezes a VGA signal and a USB signal over a single CAT5 Ethernet cable up to 120m away. The PC controlling the projector is located in a server room a long way from the projector. I have a project which controls projectors to switch them on or off via the serial port (good old RS-232). This article is also my first post to The Code Project which is my favourite resource for learning how to create cool new widgets, so I am trying to give something back to this great community. There are many useful articles already available for this. However, it will not cover any ground on WMI, neither will it show you how to use the serial port.
