Sample code Introduction

Open COM Port Device

In Sample code /LCD_CTLDlg.cpp lin 157 

  if(m_SerialPort.InitPort(this,nPort,9600,'N',8,1,EV_RXFLAG|EV_RXCHAR,512)) //Set LCM to 9600.n.8.1
  {
  m_SerialPort.StartMonitoring(); //Open Com port monitoring
  m_bSerialPortOpened=TRUE; //Set COM port open 
  }

Close COM Port Device

In Sample code /LCD_CTLDlg.cpp lin 171 

  m_SerialPort.ClosePort(); //Set COM port close
  m_bSerialPortOpened=FALSE;

Send the UP line message to LCM Device

In Sample code /LCD_CTLDlg.cpp lin 183 

  if(!m_bSerialPortOpened) return; //check the com port was open
  UpdateData(TRUE);
  char szSend[30] = {0x1b, 0x51, 0x41}; //0x1b , 0x51 ,0x41 for LCM send UPline command
  sprintf(szSend+3, "%s\r", m_Sendmsg);
  m_SerialPort.WriteToPort(szSend); //Write command and message to LCM device

Send the LOW line message to LCM Device

In Sample code /LCD_CTLDlg.cpp lin 215 

  UpdateData();
  char szSend[30] = {0x1b, 0x51, 0x42}; //0x1b , 0x51 ,0x42 for LCM send LOWline command
  sprintf(szSend+3, "%s\r", m_Sendmsg2);
  m_SerialPort.WriteToPort(szSend); //Write command and message to LCM device
