The configuration file.

When the program starts it try to read the data format, data rate and demodulator tuning from the ``./rtty.cfg'' file. This file must be located in the current directory. This is a text file like the following one:

SPACEF=950

MARKF=1800

DR=150

NBIT=8

NSTOP=1

#---- parity 0:none, 1:even, 2:odd ----

PARITY=0

As it can be seen, each line contains a VARIABLE=VALUE statement. The equal character must be always present and no spaces are allowed in the line. Comment lines start with the grid (#) character.
