Abstract
Providing a cellular telephone which does not use a digital cellular adapter and permits direct connection to an information processing apparatus for data communications. A serial data communication connection unit is directly connected to an information processing apparatus. A digital data communication processing unit interprets a command from the information processing apparatus for applying a control command to a controlling unit. Responding to the control command, the controlling unit controls a radio communication unit for issuing a call while controlling a switching unit for connection between the radio communication unit and the digital data communication processing unit thereby establishing a data communication channel. Communication data sent from the information processing apparatus is encoded by the digital data communication processing unit to be transmitted through the switching unit from the radio communication unit. Thus, the data communications are provided by directly connecting the cellular telephone to the information processing apparatus without using the digital cellular adapter.
