Hi. I was wondering if anyone can help me with this. I work at a Papa John's, and they have one server computer. They have a device coming out of the com port and it has ethernet plugs. The ethernet lines hook into the device, and they go to each of the monitors. The monitors are TeleVideo Model 990, and they have an adapter in the back. I believe that it is a com port, and the adapter converts it into a ethernet port. If anyone knows how I can make a setup like this, please let me know. I would really like to do that for my house. Thanks
