OPTIONS FILES
Options can be taken from files as well as the command line.
Pppd reads options from the files /etc/ppp/options, ~/.ppprc and
/etc/ppp/options.ttyname (in that order) before processing the
options on the command line. (In fact, the command-line options
are scanned to find the terminal name before the options.ttyname
file is read.) In forming the name of the options.ttyname file,
the initial /dev/ is removed from the terminal name, and any
remaining / characters are replaced with dots.
An options file is parsed into a series of words, delimited by
whitespace. Whitespace can be included in a word by enclosing
the word in double-quotes ("). A backslash (\) quotes the
following character. A hash (#) starts a comment, which
continues until the end of the line. There is no restriction on
using the file or call options within an options file.
