int slip_input_byte

(

unsigned char

c

)

Input a SLIP byte.

This function is called by the RS232/SIO device driver to pass incoming bytes to the SLIP driver. The function can be called from an interrupt context.

For systems using low-power CPU modes, the return value of the function can be used to determine if the CPU should be woken up or not. If the function returns non-zero, the CPU should be powered up. If the function returns zero, the CPU can continue to be powered down.

Parameters

c	The data that is to be passed to the SLIP driver

Returns

Non-zero if the CPU should be powered up, zero otherwise.
