+<h2>Description</h2>
+ The refclock_neoclock4x driver supports the NeoClock4X receiver available
+ from <a href="http://www.linum.com">Linum Software GmbH</a>. The receiver
+ is available as a <a href="http://www.dcf77.de">DCF77</a> or TDF receiver.
+ Both receivers have the same output string. For more information about the
+ NeoClock4X receiver please visit <a

+<h2>Fudge Factors</h2>
+
+<dl>
+ <dt> <b><a href="clockopt.htm">time1 time</a></b></dt>
+ <dd> Specifies the time offset calibration factor with the default value
+ off 0.16958333 seconds. This offset is used  to correct serial line and
+operating system delays incurred in capturing time stamps. If you want to
+fudge the time1 offset <b>ALWAYS</b> add a value off 0.16958333. This is
+neccessary to compensate to delay that is caused by transmit the timestamp
+at 2400 Baud. If you want to compensate the delay that the DCF77 or TDF radio
+signal takes to travel to your site simply add the needed millisecond delay
+to the given value. Note that the time here is given in seconds.</dd>
+ <dd>Default setting is 0.16958333 seconds.<br>
+ </dd>

+</dl>
+
+<dl>
+ <dt> <a href="clockopt.htm"><b>flag1 0 | 1</b></a></dt>
+ <dd>When set to 1 the driver will feed ntp with timestampe even if the
+radio signal is lost. In this case an internal backup clock generates the
+timestamps. This is ok as long as the receiver is synced once since the receiver
+is able to keep time for a long period.</dd>
+ <dd>Default setting is 0 = don't synchronize to CMOS clock.<br>
+ </dd>
+ <dd><br>
+ </dd>
+ <dt> <a href="clockopt.htm"><b>flag2 0 | 1</b></a></dt>
+ <dd>You can allow the NeoClock4X driver to use the quartz clock even if
+ it is never synchronized to a radio clock. This is usally not a good idea
+ if you want preceise timestamps since the CMOS clock is maybe not adjusted
+ to a dst status change. So <b>PLEASE</b> switch this only on if you now
+what you're doing.</dd>
+ <dd>Default setting is 0 = don't synchronize to unsynchronized CMOS clock.<br>

+ <dt> <a href="clockopt.htm"><b>flag4 0 | 1</b></a></dt>
+ <dd>It is recommended to allow extensive logging while you setup the NeoClock4X
+ receiver. If you activate flag4 every received data is logged. You should
+ turn off flag4 as soon as the clock works as expected to reduce logfile
+cluttering.</dd>
+ <dd>Default setting is 0 = don't log received data and converted utc time.<br>
