Hello,

I am developing an application in C for my Beagle Bone Black, this 
application needs to send and receive bytes through a door "/dev/ttyO4", 
however when running the command read the application locks and remains 
locked until it is stopped.

I know it's a simple thing but I've tried with several examples of the 
internet and the problem persists.

      write(fd,&cmd,1);
      char buf[1];
      sleep(1);
      int res = read(fd, &buf, 1);
