How can I update Dynamic Serialport parameters? (not baudRate)

[cjm-korea]

I'm using Node.js serialport for electron in raspberrypi4
but I can't update Dynamic parameters for serialport
only baudRate is available update.

here is my code
`
let portname, baudrate, databits, stopbits, Parity, RTSCTS;
let portOpen = false;

const port = new serialport('COM4', {
    baudRate: 9600,
    dataBits: databits,
    stopBits: stopbits,
    parity: Parity,
    rtscts: RTSCTS,
    autoOpen: false,
})
// take parameters value in other page
function getSerial() {
    const serialdata = localStorage.getItem('serialdata');
    const data = JSON.parse(serialdata);
    portname = data.portName;
    baudrate = parseInt(data.baudRate);
    databits = parseInt(data.dataBits);
    stopbits = parseInt(data.stopBits);
    Parity = data.parity;
    RTSCTS = data.RTSCTS;

}
`

I think this problem is come from port is already waiting status js is compile.
Is that right?

and I wanna know how can I update other parameters
PLEASE HELP ME

I solved this problem using global declaration and generate new serialport when button is clicked.
