Claim Text:
1. A method of setting an interface in a communication modem supporting a plurality of interfaces, the method comprises: determining, by the communication modem, a first interface mode for communicating with a device if it is detected that the communication modem connects with the device; setting integrated pins of the communication modem based on the first interface mode to receive data of the first interface mode and to prevent a reception of data of a second interface mode; waiting for a reception of data of the first interface mode for a predetermined time; determining the second interface mode for communicating with the device if data of the first interface mode is not received for the predetermined time; setting the integrated pins of the communication modem based on the second interface mode to receive data of the second interface mode; transmitting an initialization packet to determine a profile of the second interface mode through the integrated pins set to the second interface mode; and determining the profile of the second interface mode based on a voltage combination of the integrated pins on which a response of the initialization packet is received.
