PPP Routines
| Routine | Description |
|---|---|
| ppp_listen | Configures the PPP interface to accept incoming connections. |
| ppp_connect | Starts a dial-up connection to a remote PPP server. |
| ppp_close | Disconnects the PPP link. |
| ppp_is_up | Determines whether the PPP link is established and ready to use. |
note
- PPP Network Interface activates the PPP demon to start the outgoing dial-up or to listen to the incoming dial-in connections and to stop an established PPP link. The PPP Network Interface must be enabled in the configuration.
- The OS can handle simultaneous Ethernet and PPP data links. Using PPP and SLIP link at the same time is currently not supported, because both use the same serial and modem device driver.
- The PPP routines are not reentrant.
