  30  * Added #define so can select if #pragma interface/implementation is used on
  31  *   platform basis (eg MacOS) rather than compiler, thanks Robert Monaghan.
  32  *
  33  * Revision 1.2  2002/05/23 04:22:29  robertj
  34  * Fixed problem with detecting correct payload type. Must
  35  *   wait for first non-empty packet.
  36  * Added virtual function so can override record start point.
  37  *
  38  * Revision 1.1  2002/05/21 02:42:58  robertj
