Serial2.dll error (V6.01 .Net2)

[almasi]

Hi,

I have seen a binary bute transfer error in the Serial2.dll:
It seems, that using binary transfer (InputArray) the
incoming byte values 0x11 and 0x13 (decimal 17 and
decimal 19) can not be read in, these values will not
appear in the reasult array.
The serial port settings was 9600-8-N-1, but other
settings produced the same error. Other byte values are
coming perfectly, only these two bytes values are missing.
The place of these two bytes in the input stream is not
relevant: the same error comes at the beginning, middle
and at the end of the stream.

In the "old version" (V5.8, .Net 1.1, DBComm.dll, SerialDesktop.dll) this error was not present.

Please, colud you help solving this problem?

Thanks,
Bela

Those are the Xon/Xoff control byte values. It looks like you have Serial2. XonXoffHandshaking set to true.

Hi,
Thanks for the fast answer.

No, XonXoffHandshaking was explicite set to False. It seems, that the command which sets it to False has no effect. The program below put the "XonXoff True" message on the screen, so confirming that the False setting was not performed correctly:

Sport.XonXoffHandshaking = False
If Sport.XonXoffHandshaking = True Then
Msgbox("XonXoff True")
Else
Msgbox("XonXoff False")
End If

I guess, it is an error in the DLL.
Or is there any other kind of way to set the XonXoffHandshaking to False?

Bye,

Bela you are right.
There is a problem with the XonXoff property.
You could download the fixed library here : http://www.basic4ppc.com/forum/showt...=8720#post8720

It seems to be an error in the DLL! A workaround is to not set XonXoffHandshaking at all as setting it always sets it True. To be sure you could also use:-

  Sport.CTSHandshaking = False

This explicitly sets the Handshake to None if set False.


Edit :- B****r - Erel got in while I was testing and writing this
