the interface also allows a LAN enable device to access services running
on a blutooth-enabled server. The single working device of the present invention
not only provides access to an internet-connected server from a bluetooth-enabled
device but also provides transparent access to services on Bluetooth-enabled
device from an LAN enabled device or internet in such away that the two technologies
do not interfere or. disrupt the operation of each other. The present invention
