Cannot list virtual serial ports on Windows 10

[golanguage]

com0com mirror Null-modem emulator is a long history kernel-mode virtual serial port driver for Windows.

But these port cannot be detected by this lib;

serialport-rs on  main is 📦 v4.3.1-alpha.0 via 🦀 v1.78.0
❯ cargo run --example list_ports
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 1.56s
     Running `target\debug\examples\list_ports.exe`
No ports found.

I can find its port using WIN10 system serial tool:

❯ [System.IO.Ports.SerialPort]::getportnames()
CNCA0
CNCB0

Or anothere Rust serial port lib serial2.

serial2-rs on  main is 📦 v0.2.24 via 🦀 v1.78.0
❯ cargo run --example list-ports
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 1.09s
     Running `target\debug\examples\list-ports.exe`
Found 2 ports
CNCA0
CNCB0

Thank you for bringing up this issue! You are mentioning serial2 which uses different enumeration strategy on Windows. There is #84 in our PR backlog since a while, which switches to the same strategy and it looks like this could resolve your issue as well.

I would like to integrate it with with a slight change as prototyped in https://github.com/sirhcel/serialport-rs/tree/missing-modem-ports (as of 0720d5a). Could you give this branch a spin? Will it make the null-modem ports you are looking for getting listed? And what about regular serial ports: do they show up as before and as you would expect them to?

seem it's a great job.
In fact, there is not a real serial port on the PC, all 4 ports are virtual.

Solved with integrating #84.
