Hi There

In "tty.c" ttyinput() has a check for too many characters in its input
queues, as follows:

/*
  * Check for input buffer overflow
  */
 if (tp->t_rawq.c_cc + tp->t_canq.c_cc >= TTYHOG) {
  if (ISSET(iflag, IMAXBEL)) {
   if (tp->t_outq.c_cc < tp->t_hiwat)
    (void)ttyoutput(CTRL('g'), tp);
  } else
   printf("\n6\n");
   ttyflush(tp, FREAD | FWRITE);
  goto endcase;



My question is why does the "ttyflush" have FWRITE specified as well? I mean
this is an input queue problem, why flush the output queue?

It seems to me it causes output data to be unnecessarily lost?

Am I missing something here, or was it just an oversight?

Thanks!

Cheers
David
