I am compiling a project which I have modified to allow it to compile for Linux as well as Windows.
All compiles ok, except in VS6, the compiler keeps complaining about missing header files.
The headers it is looking for are the Linux ones which are ifdef'ed out (it is ignoring the ifdefs )
I have turned off precompiled headers, but this doesn't seem to have made any difference...

This seems to be happening in a different 'stage' to the Compiling/Linking, as the executable is created ok.

any ideas?

Thanks...

General linux specific header files, needed to compile the code under linux.

How are you doing that ? Post some code so that we can check.

And LINUX is only defined when compiled under linux...

Just to make a test: comment these preprocessor definition so you are 100 percent sure they won't interfere and recompile. If this doesn't work, then you probably forgot to put some of the include inside preprocessor definitions. If this works, then you probably declared LINUX somewhere and forgot to remove it.

You can also see which file generates the error, so open the file and check the include part to see if everything is correct.

Try build all or/and delete the old build files. Maybe there is an old version with the headers in it.

If it doesnt help compile every file per hand to get the source of the message.:-X

It doesn't seem to be coming from the compiler itself...
(As I said the code compiles and links correctly).
Something else is reading the source files and looking for just the #include's, and is ignoring #ifdef's etc...
I thought it was the precompiled header stuff... but even without that it still does it.

RS232 - Sending Data - Only 16Bytes allowed?!

Kreatief27-Jul-06 21:36

27-Jul-06 21:36

Hello,

I am having troubles with sending data through RS232. I am using the class from Ramon de Klein:

http://www.codeproject.com/system/serial.asp

There I am working with the simple Serial Class (Overlapped).

My problem is that I can only send 16 Byte all together. If I try to send more than 16 Byte, its sending an empty message and I get a NAK from the other side ( I monitored this with a monitoring tool).

This is what the Overlapped structure is set to after sending data:

<br />
	Internal	258	        unsigned long<br />
	InternalHigh	16	        unsigned long<br />
	Offset	        0	        unsigned long<br />
	OffsetHigh	0	        unsigned long<br />
	Pointer	        0x00000000	void *<br />
	hEvent	        0x00000780	void *<br />

As you can see, InternalHigh is set to 16. I dont know why. I cant figure out why I am only allowed to send 16 Byte. The dwInQueue as well as the dwOutQueue is big enough to hold more data.

The problem is that I absolutely have no clue where to search for that problem.

Is there anything that restricts the number of bytes to send?

Which codepart can be relevant for you?

This the write method:

<br />
LONG CSerial::Write (const void* pData, size_t iLen, DWORD* pdwWritten, LPOVERLAPPED lpOverlapped, DWORD dwTimeout)<br />
{<br />
	// Check if time-outs are supported<br />
	CheckRequirements(lpOverlapped,dwTimeout);<br />
<br />
	// Overlapped operation should specify the pdwWritten variable<br />
	_ASSERTE(!lpOverlapped || pdwWritten);<br />
<br />
	// Reset error state<br />
	m_lLastError = ERROR_SUCCESS;<br />
<br />
	// Use our own variable for read count<br />
	DWORD dwWritten;<br />
	if (pdwWritten == 0)<br />

This is how I initialize the com port:

    lLastError = rfi->serial.Open(_T("COM1"),10000,10000,true);<br />
	if (lLastError != ERROR_SUCCESS)<br />
		rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to open COM-port"));<br />
<br />
    // Setup the serial port (9600,8N1, which is the default setting)<br />
    lLastError = rfi->serial.Setup(CSerial::EBaud9600,CSerial::EData8,CSerial::EParNone,CSerial::EStop1);<br />
	if (lLastError != ERROR_SUCCESS)<br />
		rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to set COM-port setting"));<br />
<br />
	// Setup handshaking (default is no handshaking)<br />
    //lLastError = serial.SetupHandshaking(CSerial::EHandshakeHardware);<br />
	lLastError = rfi->serial.SetupHandshaking(CSerial::EHandshakeOff);<br />
	if (lLastError != ERROR_SUCCESS)<br />
		rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to set COM-port handshaking"));<br />
<br />
    // Register only for the receive event<br />
    lLastError = rfi->serial.SetMask(CSerial::EEventBreak |<br />
								CSerial::EEventCTS   |<br />
								CSerial::EEventDSR   |<br />
								CSerial::EEventError |<br />
								CSerial::EEventRing  |<br />
								CSerial::EEventRLSD  |<br />
								CSerial::EEventRecv);<br />
	if (lLastError != ERROR_SUCCESS)<br />
		rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to set COM-port event mask"));<br />
<br />
	// Use 'non-blocking' reads, because we don't know how many bytes<br />
	// will be received. This is normally the most convenient mode<br />
	// (and also the default mode for reading data).<br />
    lLastError = rfi->serial.SetupReadTimeouts(CSerial::EReadTimeoutNonblocking);<br />
	if (lLastError != ERROR_SUCCESS)<br />
		rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to set COM-port read timeout."));<br />
<br />
	// Create a handle for the overlapped operations<br />
	HANDLE hevtOverlapped = ::CreateEvent(0,TRUE,FALSE,0);;<br />
	if (hevtOverlapped == 0)<br />
		rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to create manual-reset event for overlapped I/O."));<br />
<br />
	// Setup the overlapped structure<br />
	OVERLAPPED ov = {0};<br />
	ov.hEvent = hevtOverlapped;<br />
<br />
	// Open the "STOP" handle<br />
	HANDLE hevtStop = ::CreateEvent(0,TRUE,FALSE,_T("Overlapped_Stop_Event"));<br />
	if (hevtStop == 0)<br />
		rfi->ShowError(rfi->serial.GetLastError(), _T("Unable to create manual-reset event for stop event."));<br />

I am searching for a solution for some days now, and it would be really really great to get some help, at least getting a starting point where to look at.

You can write more than 16 Bytes, I think the setup of the port.

Or the endpoint of the RS232 (the HArdware) is only liking 16 Bytes.

Can you write in 16 Byte loopes? If not there is big trouble.

No, the endpoint can handle more than 16 Bytes definetly.

I managed to write a total simple communication class which can write more than 16 Bytes. And I cant find the difference between them. I dont know where to search, and what to search for.

I believe you to change the Setup/Initialization of the Port. Compare every single value. There are some samples at CP try different to get it work.

Have you tried to write in loops???

//Meta-Code
while( DataToSend() )
{
Send16Bytes();
}

GetLastError() is also your friend!!! Mad | :mad:

Serial Port is a legacy problem so not so many know how to handle. Dead | X|

You could limit the stack and heap sizes for the application, or even write your own memory manager for it.
