This is a simple daemon for a computer running Linux to decode the DCF77, MSF
or WWVB time signal from a receiver which pulls the DCD and/or CTS pin of the
serial port high and low in correspondence with the radio signal.

Installation should be a dodle type 'make' to build the program. Provided
you have the necessary permissions on the serial port you can then test
it out. You can install the program with 'make install'. By default the
program and manual page are installed in /usr/local. This can be changed
by editing the make file.

For more details on the command line arguments to the program please consult
the manual page.

If you have problems getting the software to work using interrupts the
following, command is known to resolve the problem in many instances.

     stty crtscts < /dev/ttyS0

where ttyS0 is the serial port the receiver is connected to. You may also want
to try running

     watch -n 1 cat /proc/interrupts.

If the number of interrupts on the serial port is not steadily increasing then
there is a problem with the serial port detecting interrupts. As a last resort
you may specify a -p command line option to either program, in which case the
programs will poll the serial port every 5ms. This uses slightly more CPU time
