Redirecting the USB port for use by a program

Some improvements:

//Loopback3.js
//22 Aug 2016

//use the left pane of the WebIde or
//use putty or other termial program on com assigned to USB
//use webide to load and run the program
//disconnect webide
//start putty on com port at 115200,8 no flow control
//typing in putty should appear followed by connect in putty screen


var Sp1=USB;
var Sp2=LoopbackA;

function run(){
Sp1.setup(115200);
Sp2.setup(115200);
LoopbackB.setup(115200);
LoopbackB.setConsole();
}

function menu(){
Sp1.print("Enter 1 to turn the LED on:\n\r");
Sp1.print("Enter 2 to turn the LED off:\n\r");
Sp1.print("Enter 0 to Exit:\n\r");
}


Sp1.on('data', function (data) {
  Sp1.print(data+"\n\r"); 
  switch(data){
    case "1"://LED on
     Sp2.print("digitalWrite(B12,1);\n\r");
     Sp1.print("digitalWrite(B12,1);\n\r");
     menu();
    break;
    case "2"://LED off
     Sp2.print("digitalWrite(B12,0);\n\r");
     Sp1.print("digitalWrite(B12,0);\n\r");
     menu();
    break;
    case"0"://Exit
     Sp2.print("USB.setConsole();\n\r");
  }//end switch
});



function test(){
 run();
 menu();
}

var a=setInterval (function () {
  test();
  clearInterval(a);
}, 1000);

The output:

>echo(0);
=undefined
-> LoopbackB
Enter 1 to turn the LED on:
Enter 2 to turn the LED off:
Enter 0 to Exit:
1
digitalWrite(B12,1);
Enter 1 to turn the LED on:
Enter 2 to turn the LED off:
Enter 0 to Exit:
2
digitalWrite(B12,0);
Enter 1 to turn the LED on:
Enter 2 to turn the LED off:
Enter 0 to Exit:
0
<- LoopbackB
=undefined
=undefined
>1
