I encountered the same problem.

First I thought that devtool as REPL does not need stdin and was a simple bug in windows build. GitHub repo owners fix it just ignoring stdin on startup but, as you had discovered, devtool is broken and you can not do anything with stdin in windows.

As a proof of concept I create a simple example beyond devtool REPL:

This piece of code does not work.

//test.js
var readline = require('readline');
var rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  terminal: true
});

rl.on('line', function(line){
    console.log(line);
})

devtool test.js < input.txt

I had left a comment in your github issue but is closed so I opened a new one.
