P87C51MX: UART-1 even/odd parity

Hello 51MX users,

Has any one ever successfully used 51MX's UART-1 with either EVEN or ODD parity? My emulator does not use the 51MX chip directly, it uses the 51MX bond-out chip instead.

My UART-1 does not seem to be able to send the parity bit (bit-3, or the TB8_1 bit in S1CON) correctly. But no-parity worked OK.

Thank you in advance for any hint or answer.
