specify a communications device, usually a serial line with a modem.

+.B a
+as server, don't request authentication from the client
.TP
.B b
set the baud rate on the communications device
.TP
+.B c
+disallow packet compression
+.TP
+.B C
+disallow IP header compression
+.TP
.B f
make PPP add HDLC framing. This is necessary when using
PPP over a serial line or a TCP connection
.B m
set the maximum transfer unit (default 1450)
.TP
+.B M
+chat with the modem as specified in the chat file. Each line in
+the chat file contains a string that is transmitted to the modem
+and the response expected (e.g. 'AT' 'OK')
+.TP
.B P
use this as the primary IP interface; set the default
route through this interface and write its configuration
.I dev
instead of standard I/O
.TP
+.B S
+run as a server
+.TP
+.B t
+before starting the PPP protocol, write
+.I modemcmd
+to the device
+.TP
.B u
before starting the PPP protocol with the remote end, shuttle
bytes between the device and standard I/O until an EOF on standard
.I ppp
takes over
