method 

call to take 

effect.

NOTE: 

Base Stations using EEPROM versions prior to 9079 will cause the message "Base Reinitialized..." to 

be displayed on the terminal. Only the terminal has actually been re-initialized. Later Base Stations use the 
message "Buffer Reinitialized..." to indicate a single terminal re-initialization.
