Bus Termination

The RX, TX, and DTR pair need a 100 Ohm termination on each end of the CAT5 daisy chain. There are places on the board to solder the resistors, they are on the RPUftdi, but for an RPUadpt an RJ45 plug allows adding to the daisy chain without soldering. I'm going to supply this for now since it is how I'm using the RPUadpt board.
