This function shouldn't block. It's okay for an experiment, but it shouldn't 
say like that. It should continue processing device input as long as there is 
device input, and then return EOF.

enqueueCommand(BRL_CMD_FWINLT);
/* see brldefs.h */

>      case SCROLL_RIGHT: printf("SCROLL_RIGHT\n");break;

enqueueCommand(BRL_CMD_FWINRT);
/* yes, a lot of these could do with nicer names - blame history */

What's supposed to happen when this is done?
