)

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_IF is serial line couldn't be opened

Note:

netif->num must contain the number of the serial port to open (0 by default)

err_t slipif_output	(	struct netif *	netif,
		struct pbuf *	p,
		struct ip_addr *	ipaddr
	)

Send a pbuf doing the necessary SLIP encapsulation

Uses the serial layer's sio_send()

Parameters:

	netif	the lwip network interface structure for this slipif
	p	the pbuf chaing packet to send
	ipaddr	the ip address to send the packet to (not used for slipif)
