Module Name:

    cachemon.c

Abstract:

    This module contains the Cache Port handling for Win32Spl
    true connected printers.

Author:

    Matthew A Felton ( MattFe ) July 23 1994

Revision History:
    July 23 1994 - Created.

Notes:

    We shold collapse the LM Ports and the Win32 ports so they have use common
    ports.
