====================================



ÔHE FOLLOWING TEXT AND PROGRAM FOR DISABLING AUTO-ANSWER ON THE (OLDER) 

3 ÄÉÐ SWITCH MODEL OF THE 1670 IS FROM ÊOHN ÉANNETTA 73510,2152.



ÔHE FOLLOWING ÂÁÓÉÃ PROGRAM, WHEN ÒÕÎ, WILL CREATE AN

BE USED WITH AN EXISTING ÂÁÓÉÃ PROGRAM IN MEMORY. ÔHE ÂÁÓÉÃ PROGRAM WILL

NOT BE CORRUPTED BY DOING SO.  ÔESTING WAS ON A Ã-64.
