bool bootGetChar	(	uint8_t *	p,
		bool	flag
	)

Read byte from interface.

Parameters

[out]	p	- pointer to data buffer;
[in]	flag	- flag about unlimited or limited reading time.

Returns

true - byte was read, false - byte was not read.

bool bootScanInterfaces

(

void

)

Perform search interface activity and handshake message.

Returns

true - handshake was read, false - there is no activity.

Write byte to interface.

Parameters

[in]	len	- data length;
[in]	p	- pointer to data buffer.
