Detailed Description
Macro Definition Documentation
| #define SLIP_MAX_SIZE 1500 |
Maximum packet size that is received by this netif
Definition at line 98 of file slipif.c.
Referenced by slipif_init().
| #define SLIP_SIO_SPEED | ( | sio_fd | ) | 0 |
Define this to the interface speed for SNMP (sio_fd is the sio_fd_t returned by sio_open). The default value of zero means 'unknown'.
Definition at line 106 of file slipif.c.

Function Documentation
SLIP netif initialization
Call the arch specific sio_open and remember the opened device in the state field of the netif.
- Parameters
-
netif the lwip network interface structure for this slipif
- 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.

| void slipif_poll | ( | struct netif * | netif | ) |
Polls the serial device and feeds the IP layer with incoming packets.
