Indicates  the  acknowledgment  handling  method  (Used  for 
Addressed/Transparent Secured Mode). 
 
(Only the lower 4bits in this byte will be R/W. the upper 4 bits 
is  used  by  system  to  indicate  the  RF  acknowledgment 
status).

OK or fail signal is not sent to Host 

_ '1':  OK or fail signal will be sent to host 
 
By  default,  in  case  of  problems,  the  modem  will  retry 
automatically  for  the  numbers  (which  set  by  register  S125), 
but  doesn

t  assert  the  signals  to  host.  If  enable,  after  each 

successful  transmission,  a  Synchronize  byte  (0x16)  will  be 
sent out; if after retry still fail, a NAK byte (0x15) will be sent 
to the host.
