Abstract
A networking method and apparatus for managing information between a master device and a slave device is provided. In the network, a master device and at least one slave device are connected to each other via an RS-232 port. Through the operation of the network, the master device can obtain the identifiers (IDs) of the slave devices, and connections among the slave devices can be ascertained. Accordingly, a majority of digital home appliances establish a network using a communication medium, such as RS-232 provided to a fundamental external interface. The present invention enables digital home appliances connected on the network to exchange information.
