    June 2, 1992

    Sample program to demonstrate the use of the LAP Manager to determine the

    current AppleTalk connection device based on the ADEV resource ID.  Also 

    demonstrates a call to EGetInfo to obtain the burned in Ethernet address

    whether on the card or built-in on the Quadra's.  This program assumes the 

    use of the Apple Ethernet phase 1 0r 2 driver ADEV's.
