Need Serial Help

Here is the manual for the product that I am trying to interface with. Page 21-27 gives all of the information on the RS422 Commands, I am just interested in Record and Stop functions but am having a little trouble deciphering how to properly do this. Here is the start of my code so you may be able to get an idea for what I am trying to achieve.

//BM Recorder V1.0
int recordSw = 7;
int stopSw = 6;
int ledPin = 13;

void setup() {
  // put your setup code here, to run once:
  pinMode (ledPin, OUTPUT);
  pinMode (recordSw, INPUT_PULLUP);
  pinMode (stopSw, INPUT_PULLUP);
  Serial.begin (38400, SERIAL_8O1);
}

void loop() {
  // put your main code here, to run repeatedly:
  if (recordSw == LOW)
  {if (Serial.available())
  (Serial.print (0x200x01));
  }
}
