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.
