Point-to-Point Protocol (PPP)

The PPP feature allows serial lines to be used as network interfaces using the Point-to-Point Protocol. This feature needs to be configured for the ChorusOS operating system to fully support the various PPP-related commands provided by the ChorusOS system. These PPP-related commands are listed below:

pppstart:

Enables client PPP connections

pppstop:

Disables PPP services on the system by killing the pppstart daemon

pppclose:

Requests that the pppstart daemon close a previously opened PPP line

pppd:

Starts a PPP line

These services are complemented by chat(), which defines a conversational exchange between the computer and the modem. Its primary purpose is to establish the connection between the Point-to-Point Protocol daemon (pppd) and a remote pppd process.

The PPP feature does not export any APIs itself. It simply adds support of the PPP ifnet to the system.
