! 161: <p>The user is expected to provide a symbolic link to an available serial port device. This is typically performed by a command such as:</p>
! 162: <p><code>ln -s /dev/ttyS0 /dev/jjy0</code></p>
! 163: <p>Windows NT does not support symbolic links to device files. COM<em>X</em>: is the unit used by the driver, based on the refclock unit number, where unit 1 corresponds to COM1: and unit 3 corresponds to COM3:</p>
