EMAC has a new device called a RAD (Remote Access Device) this device can
communicate with a host over RS232/485, has provision for a keypad, and
accomadates a text or graphics LCD. The board also has an optional second
serial RS232 port that could communicate with a card scanner. Also they
have a number of single board computers with the same functionality.
