WiFly module works with telnet but not serial monitor

Wireless & IoT
1

I have a RN-XV WiFly Module - Wire Antenna (WRL-10822) connected to an Arduino pro mega 3.3V. it returns garbage in the serial monitor but works fine with the telnet. I did the “get everything” command with the telnet and that information is below. I have the module powered with a separate regulated 3.3 volt source. The module is simply wired TX to RX and RX to TX and I am not using any libraries. once the code is compiled and uploaded any value entered including “$$$” yields something like this:­óÃa?ÿkûÿd$w³ûÿ i have tried most of the baud rates and through the telnet the wiFly reports it is set at 9600. Most likely I am doing something wrong, but I do not know what it is. any help would be appreciated, thanks

void setup()
{
  Serial.begin(9600);
  Serial1.begin(9600);
  delay(500);
  Serial1.print("$$");
  delay(500);
  
}

void loop()
{
  
  if(Serial1.available() > 0) 
  {   
          Serial.print(Serial1.read());
    
  }
  if(Serial.available() > 0) 
  { 
    Serial1.write(Serial.read());
  }

}
