  It's not a good idea to change the \fBRTS\fR (or \fBDTR\fR) signal
  with active hardware handshake \fBrtscts\fR (or \fBdtrdsr\fR).
  The result is unpredictable.
+ A limitation of Windows is that the RTS and DTR lines are reset
+ when one of the -mode, -handshake, -xchar or -sysbuffer options are set. 
  The \fB-ttycontrol\fR option cannot be queried.
