+PPP Support
+-----------
+Zaptel digital cards can provide data channels through ppp as
+point-to-point connections. This requires a plugin to the ppp daemon
+that is included in the ppp/ subdirectory. To install it:
+
+1. Make sure you have the PPP source / headers installed. On Debian:
+
+   apt-get install ppp-dev
+
+2. Run 'make' on the ppp subdirectory:
+
+   make -C ppp 
+   make -C ppp install
+
+3. Make sure your kernel has support for both PPP (which is common is
+   distribution kernels and for HDLC (much less common) - CONFIG_PPP and
+   CONFIG_HDLC .
