** ===================================================================
** Method : Inhr1_RecvChar (component AsynchroSerial)
** Description :
** If any data is received, this method returns one character,
** otherwise it returns an error code (it does not wait for
** data). This method is enabled only if the receiver property
** is enabled.
** [Note:] Because the preferred method to handle error and
** break exception in the interrupt mode is to use events
** <OnError> and <OnBreak> the return value ERR_RXEMPTY has
** higher priority than other error codes. As a consequence the
** information about an exception in interrupt mode is returned
** only if there is a valid character ready to be read.
** Parameters :
** NAME - DESCRIPTION
** * Chr - Pointer to a received character
** Returns :
** --- - Error code, possible codes:
** ERR_OK - OK
** ERR_SPEED - This device does not work in
** the active speed mode
** ERR_RXEMPTY - No data in receiver
** ERR_BREAK - Break character is detected
** (only when the <Interrupt service> property
** is disabled and the <Break signal> property
** is enabled)
** ERR_COMMON - common error occurred (the
** <GetError> method can be used for error
** specification)
