So the open valve function is the following ;

private void OpenValve(string DeviceNo,bool ValvePosition)
{

string giden = "";
SendData[0] = 0xfa;
SendData[1] = Conversions.ToByte(Strings.Mid(DeviceNo, 1, 2));
SendData[2] = Conversions.ToByte(Strings.Mid(DeviceNo, 3, 2));
SendData[3] = Conversions.ToByte(Strings.Mid(DeviceNo, 5, 2));
SendData[4] = Conversions.ToByte(Strings.Mid(DeviceNo, 7, 2));
if (ValvePosition)
SendData[5] = 50;
else
{
SendData[5] = 51;
}
SendData[6] = CheckSum_Temass(5);
SendData[7] = 0xfb;



sp.Write(SendData, 0, SendData.Length);

I manage open/close valve but it takes time. I'm continuously calling OpenValve() function. It should be like when I call OpenValve() function, it should operate at first time. But it does not and cant figure out why ?

You are totally right. Before you told me I did that way and right now I solved receiving data. However there still exists problems.


I solved the problem which was relasted to parity. In default it is none but in my system it was supposed to be even. So I can receive data right now but the problem is now speed of data.

In Vb. I'm using valveopen function forthtimes to open valve.Therefore I code like ;

valveopen();
valveopen();
valveopen();
valveopen();

However in C# it is like god knows how many times it will operate :). Arbitrarily I'm able to open valve right now. All stuff are the same and no problem. I think data transfer speed of MSComn and Serial Port are different.

As you can see from Strings.Mid which Mic.VisualBasic.CompilerServices class's function.Therefore, It does not start with 0 in C#. DriverNo = "20021267" all are defined in code.

I compared sent data with C# and Vb.Net, both show the same output in text file (I wrote in a text the output). So from this point, what I've understood is the problem should be related with the output function [sp.Output(VB.Net MSComm) sp.Write(C# Serial Com))
