System to Enable Hand Held Terminal to Support Full Size Point of
Sale Input/Output Devices

      Disclosed is a method to enable full size Point of Sale (POS)
Input/Output (I/O) devices or other I/O devices on a hand held
terminal.  The hand held unit then serves two purposes:  a hand held
unit and a full size POS terminal.

      This disclosure provides a multidrop serial data connection on
the hand held that can communicate with I/O devices (keyboards,
displays, printers, etc.) that are typically used on POS devices.
The hand held  terminal's serial connector connects with a docking
station that expands  the serial link to numerous connectors for the
various I/O devices.

      The docking station can provide power to the I/O devices and
also recharge the battery in the hand held terminal.  If the hand
held terminal's battery is large enough or if the I/O device's power
consumption is low enough, the hand held terminal can power the I/O
device directly.  In addition, the I/O device could power the docking
station and charge the hand held terminal's battery.

      A low cost "dumb" POS terminal is available that is actually
just an additional set of full size I/O that is controlled by the
processor in a "master" terminal via a serial link.  The "dumb"
terminal has its own power supply for its I/O devices.  A "dumb"
terminal can have a hand held terminal's docking station attached to
its serial communication channel.  The full size I/O on the "du...
