Universal synchronous/asynchronous receiver/transmitter device driver.
The USART device driver implements buffered, interrupt controlled serial communication. It supports software and hardware handshake, 9-bit communication, half duplex and synchronous operation.
The driver's code is devided into a general part and a hardware dependant part, which simplifies porting it to different USART chips. The AVR USART Devices provide support for the ATmega128/103 on-chip USARTs.
