    • 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.
    • 提供不使用数字蜂窝适配器并允许直接连接到用于数据通信的信息处理设备的蜂窝电话。 串行数据通信连接单元直接连接到信息处理设备。 数字数据通信处理单元将来自信息处理设备的命令解释为向控制单元施加控制命令。 响应于控制命令,控制单元控制用于发出呼叫的无线电通信单元,同时控制用于无线电通信单元和数字数据通信处理单元之间的连接的切换单元,从而建立数据通信信道。 从信息处理装置发送的通信数据由数字数据通信处理单元编码,以从无线电通信单元通过切换单元发送。 因此,通过将蜂窝电话直接连接到信息处理装置而不使用数字蜂窝适配器来提供数据通信。
