How to work with COM port on node js?

Question

Node.js

All the best!
I have some kind of strange card reader, with virtually no documentation. There is a test program for Window that works with this reader (it just reads card numbers). I want to work with this reader
with the help of node js and the serialport library.
With the help of the Serial Port Monitor program , I see in the logs that when the port is opened, it seems like some flags are being transmitted, that is, not just a command is sent to the port after it is opened, but it’s like when it is opened


. But when I open the port, I don’t have such a label



Tell me where to dig?
