unsigned char usart_options_t::channelmode

Run the channel in testmode:.

• 0=normal tx/rx
• 1=auto echo(tx->rx)
• 2=local loopback(tx->rx)
• 3=remote loopback(rx->tx)

unsigned char usart_options_t::paritytype

How to calculate the parity bit:.

• 0=even parity
• 1=odd parity
• 2=space
• 3=mark
• 4|5=no parity bit
• 6|7=multidrop mode

unsigned short usart_options_t::stopbits

Number of stop bits between to characters:.

• 0=1bit
• 1=1.5bit(async mode only)
• 2=2bits
• 3 to 257 will result in a time guard period of that length between characters.
