Parameters:

netif

Returns:

ERR_OK if serial line could be opened, ERR_MEM if no memory could be allocated, ERR_IF is serial line couldn't be opened

Note:

netif->num must contain the number of the serial port to open (0 by default). If netif->state is != NULL, it is interpreted as an u8_t pointer pointing to the serial port number instead of netif->num.
