Comment 3 for bug 18274

I backed out my `115200' addition to /etc/ppp/options.ttyS0 and instead
put it in /etc/ppp/peers/ppp0 as requested but it only works
intermittently.

This is because there's various ways of going online. Using
network-admin to `Activate the modem connection' I see pppd has been
given all its options on the command line.

    root 8904 ? network-admin
    root 8907 pts/3 perl
                     /usr/share/setup-tool-backends/scripts/network-conf
                     --report
    root 9055 ttyS0 /usr/sbin/pppd /dev/ttyS0 noauth nopersist
                     nocrtscts defaultroute usepeerdns user
                     inputplus.freeserve.co.uk connect /usr/sbin/chat -v
                     -f /tmp/network-admin-chat-script-7vrIChYf4
    root 9066 ttyS0 /usr/sbin/chat -v -f
                     /tmp/network-admin-chat-script-7vrIChYf4

Without a `call ppp0' /etc/ppp/peers/ppp0 is ignored.

Going online using modem_applet does use `call' so that works.

    root 10274 ttyS0 /usr/sbin/pppd call ppp0
    root 10303 ttyS0 /usr/sbin/chat -v -f /etc/chatscripts/ppp0

As does `ifup ppp0' as root.

/etc/ppp/options{,.ttyS*} seems the right place for the baud rate since
pppd always looks there regardless of how it was started and we can't
guarantee `call' will always be used by everything.
