This error comes from the ioctl syscall when trying to change the setting of the tty device. Are you sure your device supports such operation?

This error comes from the ioctl syscall when trying to change the setting of the tty device. Are you sure your device supports such operation?

sorry for my poor knowledge abut this. blow is from AI's suggestion. the test result shows it supports.

To check if a device supports the TTY (teletypewriter) device, you can use the test command in a shell script. Here's an example using bash:

if [[ -t 0 && -t 1 ]]; then
  echo "The device supports TTY."
else
  echo "The device does not support TTY."
fi

This script checks if file descriptors 0 (stdin) and 1 (stdout) are associated with a terminal device. If both file descriptors are associated with a terminal, it means the device supports TTY.

You can run this script in your terminal to check if your device supports TTY.

here is the output of above script

What is the standard input file of your process? On macOS, usually it is the Terminal application, in which case this program silently succeeds:

$ cat a.go
package main

import (
	"os"
	"golang.org/x/term"
)

func main() {
	oldState, err := term.MakeRaw(int(os.Stdin.Fd()))
	if err != nil {
		panic(err)
	}
	defer term.Restore(int(os.Stdin.Fd()), oldState)
}

$ go run a.go 

But If you close stdin:

$ go run a.go <&-
fork/exec a: bad file descriptor

or read from a regular file:

$ go run a.go < a.go 
panic: inappropriate ioctl for device

goroutine 1 [running]:
main.main()
	/Users/adonovan/w/xtools/a.go:14 +0xf4
exit status 2

then you can't use terminal ioctls on stdin.
