[BUG] Only checks the first char of a "data" event for control chars

[TooTallNate]

I'm attempting to interact with this module programmatically (via node-pty and a child process) and noticed that I have to send the \r char separately (and after a short delay, so that the OS sends the data separately) from the rest of the payload.

So basically this does not work:

child.write('[email protected]\r');

But this does:

child.write('[email protected]');
await sleep(100);
child.write('\r');
