6170   Disable Echo Mode
Command #6170 disables the reader’s echo of received host commands. If operating 
in basic protocol or data inquiry protocol, the reader echoes by default. As the reader 
receives a host command, it echoes each character of the command. Once the entire 
command has been received and processed, the reader transmits its response. If echo-
ing is disabled with command #6170, the reader does not echo the command, but only 
transmits its response. The reader never echoes while in ECP or download mode oper-
ation.
