    Xiao,

    TRS202 has separate RX and TX lines with a flow control bit for RX and TX.
    SN65HVD82 has TX and RX on the same line.

    Controlling the signal direction and supporting RS232 flow control with be the difficult part.

    Did you plan to implement this control in hardware or software?

    The data rate speed is limited by the RS232 side and muse be same data rate and format on both sides unless software buffering is used.
