NOKIA TMR880 Programming Cable Definition

[BB101]

Does anyone know the definition of the NOKIA TMR880 programming cable or the definition of the front panel interface.
I found the relevant documents, but they don't seem to be detailed and don't have the information I need (about RXD, TXD, RTS, CTS).

The image only provides DATA and does not indicate what it is
The programming cable he is referring to should be DAU-9H
thanks

Thank you. After multiple attempts last week, I successfully connected using the FTDI232 chip with only three wires: RXD, TXD, and GND
