Remote socket (int Help)

The idea is I can set the Channel and Socket and State through Serial without writing multiple lines of (mySwitch.switchOff(4,1) OR mySwitch.switchOn(4,2)) and calling them on if statements.

So if I send SR410#
S=Set / R=Remote / 4=Channel / 1=Socket / 0=Off / #=End of msg.
Or SR321#
Set Remote Channel 3 Socket 2 Turn On.

Here is the Code.

#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch();

String inputString = "";         
boolean stringComplete = false; 

void setup() {
  
  pinMode(13, OUTPUT);
  
  Serial.begin(9600);
  inputString.reserve(200);
   
  mySwitch.enableTransmit(9);
  
}

void loop() {
    
  
  // print inputString when a # arrives:
  if (stringComplete) {
    Serial.println(inputString);
  
  // Check first letter for S or G:
  if (inputString[0] == 'S') {
    ActionSet();
  }
  if (inputString[0] == 'G') {
    ActionGet();
  }
  
  // clear the string and reset stringComplete:
    inputString = "";
    stringComplete = false;
    
  }
}

void serialEvent() {
  
  while (Serial.available()) {
    char inChar = (char)Serial.read();
    inputString += inChar;

    if (inChar == '#') {
      stringComplete = true;
    } 
  }
}


void ActionSet() {
  
  if (inputString[1] == 'R') {
    DeviceRemote();
  }
}


void ActionGet() {
  
  LedBlink();
}

void LedBlink() {
 
  digitalWrite(13, HIGH);
  delay(500);             
  digitalWrite(13, LOW); 
}


void DeviceRemote() {
  
  int Ch = inputString[2]; //Channel
  int Sk = inputString[3]; //Socket
  int Vl = inputString[4]; //Value 0 or 1 'On or Off'
   
  if (Vl == '0') {
    mySwitch.switchOff(Ch, Sk);
    Serial.println(inputString);
    LedBlink();
  }
  if (Vl == '1') {
    mySwitch.switchOn(Ch, Sk);
    Serial.println(inputString);
    LedBlink();
  }
}
