 * Copyright (C) 1985-1995 Greenleaf Software Inc.  All Rights Reserved.
 *
 * NOTES
 *
 *  This is the master include file for CommLib Level 2 functions.  You
 *  pretty much have to include this file.  It has all the prototypes,
 *  macros, and structures needed to use CommLib Level 2.
 *
 * MODIFICATIONS
 *
 * December 12, 1992  4.00A : Initial release
 *
 * December 13, 1994  5.10A : Updated to include 5.00D patch.

/*
 * If you have a custom header file that you want to include in every
 * source module in CommLib, you can automatically add it to all of the
 * library modules by simply replacing the bland GFCUSTOM.H supplied with
 * our libraries.  This will always be the first file included by any
 * of our source files, so you are guaranteed specific behavior.  See
 * header file memchk.h for an example of how to build a version of
 * commlib that is linked to memcheck.

/*
 * People wonder why COM1 is an int instead of a macro.  The reason goes back
 * to the cutover to Commlib 3.2.  Lots of functions that used to take an
 * int port number in 3.1 changed to taking a PORT structure pointer in
 * 3.2.  Normally, if you try to pass an int as a pointer you will get an
 * error, so users that didn't update their code properly could count on
 * getting an error from the compiler.  However, COM1 is defined as 0, and
 * 0 is a special value that can be passed as a pointer.  So defining it
 * as an extern int avoids that particular problem, and will cause an
 * error if somebody tries to pass COM1 as an argument to ZmodemSend().
