uiflow 2.0 with coreS3 and RS232 Module / UART

[trackmaxx]

I try to connect to the RS232 Port of RS232 Module 13.2 with DB9 Male Connector. But always fail with error message "ValueError: invalid pin".
I use
uart2 = UART(2, baudrate=9600, bits=8, parity=None, stop=1, tx=17, rx=16, rts=-1, cts=-1, txbuf=256, rxbuf=256, timeout=0, timeout_char=0, invert=0, flow=0)
same with rx/tx 13/14.
Any idea what's wrong and how I can communicate with the port?
Thanks, Mike

@felmue thanks a lot! Now it works. Just to know for others with the same problem : The uiflow2 uart command doesn't work.
