So, this set of patches may be applied to the pppd process to enable
appropriate Makefile in the pppd subdirectory to add "-DCBCP_SUPPORT"
to the CFLAGS definition and add cbcp.o to the list of object files,
and then recompile pppd. The patch below does this for Makefile.bsd
-and Makefile.linux.
+and Makefile.linux. You can patch the Makefiles by running
+patch -p1 < README.cbcp.
+I use such script to make a callback:
+
+pppd debug nodetach /dev/modem 115200 crtscts modem \
+callback 222222 name NAME remotename SERVER \
+connect 'chat -v "" atz OK atdt111111 CONNECT ""'
+sleep 1
+pppd debug /dev/modem 115200 crtscts modem \
+name NAME remotename SERVER defaultroute \
+connect 'chat -v RING ATA CONNECT "\c"'
+
+First we invoke pppd with 'nodetach' option in order to not detach from
+the controlling terminal and 'callback NUMBER' option, then wait for
+1 second and invoke pppd again which waits for a callback (RING) and
+then answers (ATA). Number 222222 is a callback number, i.e. server will
+call us back at this number, while number 111111 is the number we are
+calling to.
+
+You have to put in /etc/ppp/chap-secrets the following two lines:
+
+NAME SERVER PASSWORD
+SERVER NAME PASSWORD
+
+You have to use your real login name, remote server name and password.
