Function Documentation

◆ sio_flush()

void sio_flush ( void  )

Flushes the input buffer.

Referenced by sior_rpc_server().

◆ sio_getc()

int sio_getc ( void  )

Referenced by sior_rpc_server().

◆ sio_getc_block()

int sio_getc_block ( void  )

Same as sio_getc, but blocking. Note that getc should be blocking by default. Ho well.

Referenced by sior_rpc_server().

◆ sio_gets()

char* sio_gets ( char *  str)

Will block until it recieves
or \r.

Referenced by sior_rpc_server().

◆ sio_init()

void sio_init ( u32  baudrate,
u8  lcr_ueps,
u8  lcr_upen,
u8  lcr_usbl,
u8  lcr_umode 
)

Referenced by sior_rpc_server().

◆ sio_putc()

int sio_putc ( int  c)

Referenced by sior_rpc_server().

◆ sio_puts()

int sio_puts ( const char *  str)

Referenced by sior_rpc_server().

◆ sio_putsn()

int sio_putsn ( const char *  str)

Referenced by sior_rpc_server().

◆ sio_read()

size_t sio_read ( void *  buf,
size_t  size 
)

This will read from the serial port until size characters have been read or EOF (RX FIFO is empty).

Referenced by sior_rpc_server().

◆ sio_write()

size_t sio_write ( void *  buf,
size_t  size 
)

Not really much to do in the way of error-handling. sio_putc() already checks to see if there's room in the TX FIFO, and my cable doesn't support hardware flow control.
