Strange serial characters on Serial

I have an Espruino hooked up to pin 0RX and 1TX pin on my Edison Arduino breakout board.  I am receiving strange characters(please see picture below) along with the actually readable characters(I2C,99). I have no idea why I am receiving the strange characters and I am not sure how to troubleshoot this further.  To troubleshoot this issue, I stopped the sending of characters from the Espruino, but I still get the strange characters. I also disconnected the Espruino and connected a FTDI to the Serial input and output and I am still receiving the strange characters even when I am not sending text to the RX pin.

My question is, why am I receiving the strange characters and what do I need to do to fix this issue?

My pin mappings are as follows:

#!/bin/sh

 

# export all useful gpio

echo 130 > /sys/class/gpio/export

echo 248 > /sys/class/gpio/export

echo 216 > /sys/class/gpio/export

echo 131 > /sys/class/gpio/export

echo 249 > /sys/class/gpio/export

echo 217 > /sys/class/gpio/export

echo 214 > /sys/class/gpio/export

 

# Disable tri-state

echo low > /sys/class/gpio/gpio214/direction

 

# Set direction

echo low > /sys/class/gpio/gpio248/direction

echo high > /sys/class/gpio/gpio249/direction

 

echo in > /sys/class/gpio/gpio216/direction

echo in > /sys/class/gpio/gpio217/direction

 

# Set Mode1

echo mode1 > /sys/kernel/debug/gpio_debug/gpio130/current_pinmux

echo mode1 > /sys/kernel/debug/gpio_debug/gpio131/current_pinmux

 

# Activate tri-state

echo high > /sys/class/gpio/gpio214/direction

my nodejs code:

var SerialPort = require("serialport").SerialPort;
var port = "/dev/ttyMFD1";
var serialPort = new SerialPort(port, {        baudrate: 9600
}, false);

console.log("Open port: "+ port);
serialPort.open(function (error) {
        if (error) {                console.log('Failed to open: '+error);        } else {                console.log('open');                serialPort.on('data', function(data) {                        console.log('data received: ' + data);                });                //write data to serial port every second                var counter = 90;                setInterval(function () {                        serialPort.write(String(counter)+ "\r\n", function(err) {                                if(err) {                                        console.log('err ' + err);                                }else{                                        console.log('Writing data ');                                }                        });                        counter++;                        if(counter>100)                                counter =90;                }, 1000);        }
});

Espruino javascript code:

function onInit() {  Serial2.setup(9600/*baud*/);
}

Serial2.on('data', function (data) {
  console.log(data +"\r\n");
});

onInit();

setInterval(function (e) { Serial2.print("I2C,99\r\n"); }, 3000);
