/*
 *
 * REVISIONS:
 *  TSC17May93: Added SmartSerialPort :: SYSTClosePort()
 *  TSC31May93: Added define for _theConfigManager, changed SmartSerialPort
 *                       to native NT, added error logging
 *  rct03Nov93: Broke off from port.cxx
 *  cad08Dec93: slight interface changes, added constructors
 *  cad04Jan94: added debug flags
 *  pcy08Feb94: #if UNIX around theRLock
 *  rct07Mar94: Re-Added SimpleSerialPort::Close()
 *  jps14Jul94: commented out INCL_NOPMAPI; put os2.h inside extern "C"
 *  daf25Nov95: support for PNP cable   
 *  srt24Jan96: Windows specific functions moved into w31port.cxx  
 *  srt24Jan96: added theCableType field initialization on windows
 *  pav16Jun96: #ifdef !NT constructors that NT doesn't use
 *  dml17Jun96: Added missing return value for GetCableType
 *  pcy28Jun96: Initialize file handle so we dont crash
 *  cgm05Jul96: Changed Simple::Initialize to check Open() error code
 *  poc28Sep96: Added valuable debugging code.
 *  mds28Dec97: Initialized FileHandle to INVALID_HANDLE_VALUE in SimpleSerialPort
 *              constructor (for NT)
