	/* Comm. Protocol Version in force when this

	 * changes, even if this software did not change.
	 * For Protocol Version ID, see the Exchange
	 * Communications Protocol document.
	 * This is in the C file instead of the header
	 * file 'cause the header file is used by other
	 * C files, which could compromise encapsulation.
	 * v1 - original version
	 * v2 - added the Query Edit Flash Permission command.
	 * v3 - added the Query Max Data Block Size command
	 *      and redesigned to eliminate RTDX comm..
