lyc - Linux Yamaha receiver control (over serial / RS232 interface)

Yamaha RX-V3800 and some older models like DSP-AX1 are great AV-Receiver, but unfortunately they have no control / web interface to manage it from outside. With a USB-Serial adapter connected to the reciver RS-232 interface, a computer or router and lyc you can control the reciver. In addition, a web interface can be created with wlyc to provide a web access to all network devices like PC, smartphone or tablet.
