How to use this Demo Application
1.Selcet RS485 com port and Rts Signal Control ,Click Open.
2. Put some message in editbox and then press send button
3.Click Recive button and than the message will display in editbox.
4.click AutoFlow if you want to test flowcontrol.
Sample code Introduction
Create Com Port
bool CreatCom(CString Com_Str,DWORD Send_buf,DWORD Rec_buf,int flow_control)
Parameters
Com_Str: The name of COM port to be created
Send_buf:Setting Send buffer
Rec_buf: Setting Recive buffer
flow_control:flow control flag :1(on) or 0(off)
Setting Com port
bool SetCom(int rate, BYTE ByteSize, TCHAR parity, TCHAR stopbit, int rtsflag)
Parameters
rate:Specifies the device communication BaudRate.
parity:'E'=EVENPARITY , 'M'=MARKPARITY , 'N'= NOPARITY , 'S'= SPACEPARITY , 'O' = ODDPARITY
stopbit:'1'=ONESTOPBIT , '1.5'=ONE5STOPBITS , '2'=TWOSTOPBITS
rtsflag: 0=no setting(RS232) , 1=default RTS is low , 2=default RTS is high
Send Message or Recive Message
bool Send(CString)
bool Recive(CString *)
If successful return true else return false
Close Com handle
bool CloseCom()
Closes a COM handle. if function success , return true.
Close Com handle
LPCTSTR GetErrMsg()
