Setting serial RS232 port settings; any in C# alternatives to SerialPort class ?
- by adrin
In my .NET application I need to achieve serial port setup equivalent to this C++ managed code:
::SetCommMask(m_hCOMM, EV_RXCHAR);
::SetupComm(m_hCOMM, 9*2*128*10, 400);
::PurgeComm(m_hCOMM, PURGE_TXABORT|PURGE_RXABORT|PURGE_TXCLEAR|PURGE_RXCLEAR);
COMMTIMEOUTS timeOut;
timeOut.ReadIntervalTimeout = 3;
timeOut.ReadTotalTimeoutConstant = 3;
timeOut.ReadTotalTimeoutMultiplier = 1;
timeOut.WriteTotalTimeoutConstant = 0;
timeOut.WriteTotalTimeoutMultiplier= 0;
int nRet= ::SetCommTimeouts(m_hCOMM, &timeOut);
::EscapeCommFunction(m_hCOMM, SETDTR);
::EscapeCommFunction(m_hCOMM, SETRTS);
DCB dcb;
memset(&dcb, 0, sizeof(DCB));
dcb.BaudRate= m_nSpeed;
dcb.ByteSize= 8;
dcb.fParity = FALSE;
dcb.Parity = NOPARITY;
dcb.StopBits= ONESTOPBIT;
dcb.fBinary = TRUE;
dcb.fDsrSensitivity= FALSE;
dcb.fOutxDsrFlow= FALSE;
dcb.fOutxCtsFlow= FALSE;
dcb.fDtrControl = DTR_CONTROL_HANDSHAKE;
dcb.fRtsControl = RTS_CONTROL_TOGGLE;
nRet= ::SetCommState(m_hCOMM, &dcb);
Is it possible at all? How do I approach this problem? Are there any (preferable free) libraries that allow such low level serial port control or should I create my own wrapper on top of Win32 api?
Anyone did anything similar or has an idea how to 'glue' win32 serial port api with .net so that I can use neat .NET DataReceived() events ? Or maybe I can create .NET SerialPort instance and then modify it using managed API?
