Function Documentation

◆ async_rx_init()

async_rx_state_t * async_rx_init ( async_rx_state_t s,
int  data_bits,
int  parity_bits,
int  stop_bits,
int  use_v14,
put_byte_func_t  put_byte,
void *  user_data 
)

Initialise an asynchronous data receiver context.

Initialise an asynchronous data receiver context.

Parameters
sThe receiver context.
data_bitsThe number of data bits.
parity_bitsThe type of parity.
stop_bitsThe number of stop bits.
use_v14TRUE if V.14 rate adaption processing should be used.
put_byteThe callback routine used to put the received data.
user_dataAn opaque pointer.
Returns
A pointer to the initialised context, or NULL if there was a problem.

◆ async_tx_init()

async_tx_state_t * async_tx_init ( async_tx_state_t s,
int  data_bits,
int  parity_bits,
int  stop_bits,
