send the packet again.  When ARQ is enabled, the transmitting radio will attempt to send a 
packet packet attempts limit times before discarding the packet.  A value of 
00H
 disables 
ARQ.  When it is disabled, any transmission received with errors is discarded. It is the 
responsibility of the user application to track missing packets.  A second parameter, ARQ 
Mode,
 allows the choice between using ARQ to resend unsuccessful transmissions or always 
sending a transmission packet attempts limit times regardless of the success or failure of any 
given transmission. 
 
All of this error detection and correction is transparent to the user application.  All the user 
application sees is error-free data from the modem.  However, if the ARQ mode is disabled, 
transmissions with errors are discarded, and missing data detection will be the responsibility 
of the user application.  Refer to the Protocol Commands section for complete details.
