How to link a couple of fake ttys in Linux/macOS

Could you confirm support for something like below? 

```
socat -d -d \
    pty,raw,nonblock,echo=0,iexten=0,link=/tmp/tty.fake.slave \
    pty,raw,nonblock,echo=0,iexten=0,link=/tmp/tty.fake.master &
```

This is currently used to test serial communication protocols on macOS but I am moving to M1 silicone where brew/ports are not fully supported yet making socat not readily available.
