What steps will reproduce the bug?

Running the programme for the first time.

What happens?

var port1 = new SerialPort({ path: 'COM1', baudRate: 9600, autoOpen: true })
var port2 = new SerialPort({ path: 'COM2', baudRate: 9600, autoOpen: true })
var port3 = new SerialPort({ path: 'COM3', baudRate: 9600, autoOpen: true })
var port4 = new SerialPort({ path: 'COM4, baudRate: 9600, autoOpen: true })

I have four serial ports. when I check them in the device manager I see that their names are COM1, COM2, COM3 and COM4. Sometimes I can only connect to COM3. Sometimes I can connect to COM1, COM3, COM4 and not COM2, sometimes I can connect to all of them. When I restart the programme I see that it connects to all of them.

What should have happened?

I had to connect to all of them.

Additional information

The same javascript file runs smoothly on 2 different computers (identical computers) that I have previously prepared.

I encountered the problem for the first time. Ports are available but not connected. When I restart, I see that they are all connected.

I need to connect the first time.
