PPP is the protocol used for establishing Internet links over dial-up modems, DSL connections, andExtends other types of point-to-point links. The pppd daemon works together with the kernel PPP driverTo establish and maintain a PPP link with another system (called the peer) and to negotiate InternetProtocol (IP) addresses for each end of the link. p

, called "stream interface functions ". Applications can access these interface functions through file system interface functions (APIS) to call drivers and drive hardware devices. In the stream interface driver, the driver abstracts peripherals into a file, and the application uses the API provided by the operating system to access peripherals. The stream interface driver supports almost any type of external devices that can be connected to the Windows CE.net platform, such as printers and
other is dual-port Memory RAM. If the port is used, at least two ports are used to transmit at commands in the CS domain and data related to data transmission in the PS domain. The visual phone needs to add a VT port. This function is used to transmit local and peer visual phone data on the AP and modem sides.[Edit] 2

Leased Line/dial-up leased line: refers to two common passive (or active) wires. There is no dialing sound for dialing on the leased line, so dedicated hardware support is required. A dial-up line is a common telephone line, which is called by the telephone system. Common modems support dial-up lines rather than leased lines.
