USART3 at 7E1 problem

''It 's not defined the option USART_WordLength_7b''

Are you sure that the hardware supports it? What does the Datasheet/User Manual say?

Do you think USART is correctly programmed for 7E1 conditions?

No. Parity might appear to ''work'' for about half the bit patterns, and the stop bit is a problem. Once the receiver registers a parity error, that needs to be cleared before more data arrives. You'd be better to program the USART as 8N1, and create the ''parity'' bit in software (ie  7+1 bits = 8 bits)
