We plan to buy colored wall plates (I believe shocking orange is one option), and we'll place the data terminal plugs right next to the phone outlets, which will be clearly marked. If users insist on plugging in their terminals to the phone plugs, I won't be real sympathetic when they complain... Lastly, we intend to use 6 leads, as that will provide some method of telling our data PBX that a PC has been re-booted while in terminal emulation.
