I switched from canonical to non-canonical input mode.
res= 9 myresponse[ 0]=[fe] myresponse[ 1]=[fe] myresponse[ 2]=[80] myresponse[ 3]=[e0] myresponse[ 4]=[14] myresponse[ 5]=[0a] myresponse[ 6]=[00] myresponse[ 7]=[32] myresponse[ 8]=[fd]
Now I can get rid of my dirty hack described in my previous articleTX power control does not work.
