Okay I could really use some help and need someone experienced enough to point out where I am going wrong here. I am trying out serial communication for the first time, and haven't done much programming in C#. I am using Visual Studio 2010 and I have "Head First C#: 2nd Edition" by O'Reilly for C# & .NET 4.0 on Visual Studio 2010.
Anyways, I have made a simple 4 button 2 text box program to try and communicate with my Moates Demon. I have my button orders all messed but here is what I have so that it makes sense: Button 1 = Send, Button 2 = Connect, Button 3 = Disconnect; Button 4 = About. TextBox1 = Read Only for Received Data; TextBox2 = Input for sent data.
Heres what it will do. It WILL connect, and it WILL disconnect. As far as I know it IS sending data, as I input 56 to get the version and it is sending 2 of the same bytes. I get no errors, if I input just 'V' in the text box2 it will catch an error about the input type, if I leave it null it does the same. Anyways so if I get zero errors and it seems like it sends, I get NOTHING in return, or I am getting returned data that isn't in a format I can view. I am absolutely not sure which problem it is, but it is displaying NOTHING in my textbox1. I have set it to append, and to just set to equal.
Here is all of my codes in Visual Studio.
