*       This file contains all configuration options used by PPP. These can
*       be modified in order to fit the specific needs of the applicaiton.
*       All constants that are prefixed HDLC_ affect only serial devices,
*       while constants prefixed with PPE_ affect only PPPoE devices. If
*       you do not have the optional Nucleus PPPoE library, you can ignore
*       all PPE_ constants.

/* These defines are used for debugging.

   _PRINT          will direct where to print the above information.

   DEBUG_PKT_TRACE will capture all packets sent and received. They
                   are stored in an array defined in PPP.C

   PKT_TRACE_SIZE  defines the size of the packets trace buffers. Note

1)
You can direct the output to printf.


#define _PRINT printf

2)
Or you can use this method to send it to a memory buffer. You will
need to define the two variables below in your application or some
other source file for this to work. Also, this method will not work
for print statements that try to print varialbes. This is done in
two places in the PPP source code. You will need to comment out
those lines for this to compile. The files are MDM.C and NCP.C.
Search for _PRINT.
