//  History:
//  --------
//
//    02.04.2003: The original IrDA socket support class was written
//                to use in ATL/WTL applications. Modified the class
//                so that it can be used in every MFC application.
//
//    03.04.2003: Added the "VerifyService" function.
//
//    16.04.2003: Added a second "VerifyService" function and modified
//                the original "VerifyService" function.
