Reference Guide
lcp-max-configure n
Sets the maximum number of LCP configure-request
transmissions to n (default 10).
lcp-max-failure n
Sets the maximum number of LCP configure-NAKs.
lcp-max-terminate n
Sets the maximum number of LCP terminate-request
transmissions to n (default 3).
lcp-restart n
Sets the LCP restart interval (retransmission time-out) to n
seconds (default 3).
local
Do not use the modem control lines. With this option, pppd
ignores the state of the CD (Carrier Detect) signal from the
modem and does not change the state of the DTR (Data Terminal
Ready) signal.
maxconnect n
Terminates the connection when it has been available for network
traffic for n seconds; that is, n seconds after the first network
control protocol comes up.
modem
Use the modem control lines. This option is the default. With this
option, pppd will wait for the CD (Carrier Detect) signal from the
modem to be asserted when opening the serial device (unless a
connect script is specified), and it will drop the DTR (Data
Terminal Ready) signal briefly when the connection is terminated
and before executing the connect script.
netmask n
Sets the interface netmask to n, a 32-bit netmask in decimal dot
notation (for example, 255.255.255.0). When this option is given,
the value specified is ORed with the default netmask. The default
netmask is chosen based on the negotiated remote IP address; it is
the appropriate network mask for the class of the remote IP
address, ORed with the netmasks for any non-point-to-point
network interfaces in the system that are on the same network.
