+How it works
+</p>
+
+<p>
+The program 'datenklo' is an emulator for the original "CCC modem", a building instruction released by the Chaos Computer Club in 1985.
+The heart of this software is the AM7911 modem chip emulation.
+It modulates digital levels to FSK tones and demodulates FSK tones to digital levels.
+A software UART (serial transceiver) converts characters (bytes) into levels and leves into bytes.
+The modem chip emulation is linked to sound card via ALSA driver.
+The UART is linked to a tty emulation.
+The tty emulation uses FUSE, so that the linux kernel provides a virtual serial interface. (/dev/ttyDATENKLO0 by default)
