** Method : AS1_RecvBlock (component AsynchroSerial)
** Description :
** If any data is received, this method returns the block of
** the data and its length (and incidental error), otherwise it
** returns an error code (it does not wait for data).
** This method is available only if non-zero length of the
** input buffer is defined and the receiver property is enabled.
** If less than requested number of characters is received only
** the available data is copied from the receive buffer to the
** user specified destination. The value ERR_EXEMPTY is
** returned and the value of variable pointed by the Rcv
** parameter is set to the number of received characters.
** Parameters :
** NAME - DESCRIPTION
** * Ptr - Pointer to the block of received data
** Size - Size of the block
** * Rcv - Pointer to real number of the received data
** Returns :
** --- - Error code, possible codes:
** ERR_OK - OK
** ERR_SPEED - This device does not work in
** the active speed mode
** ERR_RXEMPTY - The receive buffer didn't
** contain the requested number of data. Only
** available data has been returned.
** ERR_COMMON - common error occurred (the
** GetError method can be used for error
** specification)
