If it helped, try to move it below the first read

while ( 1 ) {
         ret = read ( fileno(stdin) , &(buf[0]), 1);
         fcntl ( fileno(child_recv), F_SETFL, O_NONBLOCK);
         if ( ret == 0 ) break; /* Pipe was closed by parent -> quit */
         if ( ret == 1 ) {

otherwise the form is not updated and cannot be edited.
