Not able to obtain reading from RX of arduino

Other Hardware General Electronics
14 
#include <SoftwareSerial.h>
#include <LiquidCrystal.h>

char SBUF0 = 0;
SoftwareSerial mySerial(10, 11); // RX, TX

LiquidCrystal lcd(12, 11, 5, 4, 3, 2); 

void setup()
{
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  mySerial.begin(1200);

  lcd.begin(16, 2);
  lcd.print("lcd");
 // lcd.print(SBUF0);
}

void loop()
{
  Ht9032_get();
  Serial.print(SBUF0);
//  lcd.setCursor(0, 1);
  // print the number of seconds since reset:
  //lcd.print(millis() / 1000);
}


void Ht9032_get()
{
  while (mySerial.available() > 0)
  {
    //Serial.flush();
    SBUF0 = Serial.read();
    Serial.print((float)SBUF0);
    lcd.print(SBUF0);
  }
}

In my serial monitor, I obtain some symbols like "///////////////////////////////////////////////"
How do I convert into useful information.
