In the following script, stdin and stdout are both assumed to be connected to a terminal.
Bytes are read from stdin and written to stdout until the return key is pressed.
<lang ecmascript>import "io" for Stdin, Stdout
Stdin.isRaw = true // prevents echoing to the terminal
while (true) {
var byte = Stdin.readByte() // read a byte from stdin
if (byte == 13) break // break when enter key pressed
System.write(String.fromByte(byte)) // write the byte (in string form) to stdout
Stdout.flush() // flush output
}
System.print()
Stdin.isRaw = false</lang>
