The ACCM is a set of 32 bits, one for each of the ASCII controlĬharacters with values from 0 to 31, where a 1 bit indicates that the corresponding control character should not be used in PPP packets sent to this system. Linux, SunOS) only support the commonly-used baud rates.Īsyncmap map This option sets the Async-Control-Character-Map (ACCM) for this end of the link. On systems such as 4.4BSD and NetBSD, any speed can be Speed An option that is a decimal number is taken as the desired baud rate for the serial device.

A value for this option from a privileged source cannot be overridden by a Pppd will use that terminal, and will not fork to put itself in the background. If no device name is given, or if the name of the terminal connected to the standard input is given,

To ttyname to form the name of the device to open. If ttyname does not begin with a slash (/), the string '/dev/' is prepended With other network protocols besides IP, but such use is becoming increasingly rare.įrequently Used Options ttyname Use the serial port called ttyname to communicate with the peer. Pppd can also authenticate the peer and/or supply authentication information to the peer.

Protocol (IP) addresses for each end of the link. The pppdĭaemon works together with the kernel PPP driver to establish and maintain a PPP link with another system (called the peer) and to negotiate Internet

PPP is the protocol used for establishing internet links over dial-up modems, DSL connections, and many other types of point-to-point links.
