Thanks for your help. I'll try 38400 tonight and see how it goes. Also in the following from the pin definitions:
/* Ports for soft UART */
#ifdef SOFT_UART
#define UART_PORT PORTD
#define UART_PIN PIND
#define UART_DDR DDRD
#define UART_TX_BIT 1
#define UART_RX_BIT 0
#endif
#endif
I don't understand what PIND and DDRD are for. Any idea? Thanks again.
