-	  <para>The third serial port, <filename>sio2</filename>,
-	    or <filename>COM3</filename>,
-	    is on <filename>/dev/cuad2</filename> for dial-out
-	    devices, and on <filename>/dev/ttyd2</filename> for
-	    dial-in devices.  What is the difference between these two
-	    classes of devices?</para>
-
-	  <para>When
-	    opening <filename>/dev/ttydX</filename> in blocking mode,
-	    a process will wait for the corresponding
-	    <filename>cuadX</filename> device to become inactive, and
-	    then wait for the carrier detect line to go active.  When
-	    the <filename>cuadX</filename> device is opened, it makes
-	    sure the serial port is not already in use by the
-	    <filename>ttydX</filename> device.  If the port is
-	    available, it steals it from the
-	    <filename>ttydX</filename> device.  Also, the
-	    <filename>cuadX</filename> device does not care about
-	    carrier detect.  With this scheme and an auto-answer
-	    modem, remote users can log in and local users can still
-	    dial out with the same modem and the system will take care
-	    of all the conflicts.</para>
