-The pppd program comes from the free distribution of PPP for Suns and
-386BSD machines, maintained by Paul Mackerras. This package lists
-"thanks to" Brad Parker, Greg Christy, Drew D. Perkins, Rick Adams and
-Chris Torek.
-
-Jim Freeman added the code to support a ppp module and to dynamically
-extend the number of ppp devices. All ppp devices listed in the Space.c
-will be unlinked when the kernel is loaded. This feature makes the use
-of '16 channel' support obsolete.
-

-
-CHANGES FROM THE PREVIOUS VERSION
-
-- The number of devices for the PPP device has been made dynamic. It was
- previously configured with the default value of four devices.
-
-- The problems dealing with other systems such as Windows NT and their
- authenticiation has been corrected. It will now generate the proper
- responses to allow the system to choose a valid authentication protocol.
-
-- The kernel debug value has changed. Previously it was a level. It is now
- a bit map with various bits meaning certain types of debug information.
-
- 0 - No debug information is generated
- 1 - Debug messages
- 2 - Log incoming packets
- 4 - Log outgoing packets
- 8 - Log tty output buffers
- 16 - Log tty input buffers
-
- If you wish to use any combination, add the values together. For example,
- '7' will log debug messages and incoming packages and outgoing packets.
-
- The default setting is 0.
-
- The simple IP trace which ppp.c performed when 'kdebug' was greater than
- 127 has been removed. You should use tcpdump for this type of trace
- actions.
-
-- Support is added for compression control protocol. At the present time
- only the BSD-Compress compression protocol is supported.
-
-- There are two queues for output frames. This avoids some problems which
- occured with the previous version and some PPP packages which exchanged
- echo frames with Linux.
-
-- The echo frames are now proper. Previously, it would generate extra
- characters and this caused some providers to not respond to the 'junk'.
-
-- The max-echo-failure option will now properly disconnect the line.
