Ive made the changes that you suggested and edited the question for more clarity. Thanks for all your help as your suggestions gave me the correct translation but it seems that the problem is much deeper because the serial device still wont communicate even though the output from a loopback test delivers the correct commands. My next step will be to try in a separate thread will be new for me.

Posted a new question with my change if you have time to check out:
http://www.codeproject.com/Questions/1008564/How-to-get-Characters-Get-Bytes?arn=0

WinForms but it is in .net 2.0 framework. Not sure if that matters

Im sorry but I would have no idea how to make that happen. Like I said, I have little experience. If you'd be willing to show me Id extremely appreciate it

Ok, Ill make that read in change, but where would you recommend I make the execution because I want the array command sent after I click on the link label.

http://www.codeproject.com/Questions/1008236/Sending-ASCII-Controls-STX-and-ETX

I am placing this is in wrong?

private void linkLabel_HC1_100_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
private const byte stx = 0x02;
private const byte etx = 0x03;
private byte[]WrapString(string send)
{
int length = send.Length;
byte[] data = new byte[length + 2];
data[0] = stx;
data[length + 1] = etx;
Array.Copy(System.Text.Encoding.ASCII.GetBytes(send), 0, data, 1, length);
return data;
}
byte[] data = WrapString("01P00102##");
}

Checked the setting and they are the same as the working terminal. Any chance you code show me how to make it a byte array?

Invalid Operation Exception was unhandled under sport_Data Recieved.
Additional information: Cross-thread operation not valid: Control 'txtReceive' accessed from a thread other than the thread it was created on.

Not sure what that means but was the char items placed correctly?

I thought that with little to no experience that I may have more luck finding an application which already exists in this format rather than creating my own serial port terminal. Is it simple to learn and create with the specifications I want?

Yeah you are right about the time spent versus paying for the software. Thankfully I received the command set and was able to conduct commands from a host laptop. Thanks for the help

Thanks for the steps. I received the manufacture's command set and followed your outline and was able to conduct its movement. Obviously you were right, I wouldn't have stood a chance without their command protocol

Business project. The inventory is within a storage warehouse. The storage system's company provides software to purchase that will allow this host connection I speak of but I am conducting research to understand if I am capable of programming it myself to avoid expanding my department's budget
