LoopbackB.setConsole() InternalError in TCP connection (Espruino WiFI)

Great!

In an ideal world I'd be able to make the Telnet service low-level enough that it could survive a reset. It's on my Todo list for Espruino WiFi, but it's not straightforward!

I think the easiest option is just to make reset do something different on Espruino:

global.reset=function() {
  clearWatch();
  clearInterval();
  console.log("-= RESET =-");
}

Just to post up the complete code that I have (in case it's useful for anyone):

var WIFI_NAME = "";
var WIFI_OPTIONS = { password : "" };

var wifi = require("Wifi");
wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
  if (err) {
    console.log("Connection error: "+err);
    return;
  }
  console.log("Connected!");
  wifi.getIP(print);
  
  require("net").createServer(function(conn) {
    conn.on('close', x=>USB.setConsole());
    conn.pipe(LoopbackA);
    LoopbackA.pipe(conn);
    LoopbackB.setConsole();
  }).listen(23);
});
global.reset=function() {
  clearWatch();
  clearInterval();
  console.log("-= RESET =-");
};

It would actually be possible to check process.env.CONSOLE=="LoopbackB" inside reset and to avoid doing a reset only in the cases where code was uploaded over WiFi.
