The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Sending ASCII strings to an IP device in VB.net 2003 aspx web application

Asked by hagoog in .NET Framework 1.x, Programming for ASP.NET, Microsoft Visual Basic.Net

Tags: VB.net 2003

I have an IP device on the network that I need to make a web app for. The web app needs to send ascii text strings to the IP address of the device. This device has RS232 and IR ports on it to control electronics. When the right ascii code is sent to the device via IP it then relays the rs232 or IR to accomplish the goal of the command. I need only to send ascii messages to the ip address according to the API into in the code window.

In the code window I am putting the documentation that have on the API

I need to be able to send the strings on button clicks etc in the web app and allow parameters of the string to be built dynamically.

The part I need to understand is how is an ascii string sent to an ip address
What code is needed to do this?
Thanks!

             Communication with the GC-100 is accomplished by opening a TCP socket on Port 4998. All commands and data, with the exception of serial (RS232) data, are communicated through Port 4998. Port 4998 is used for such things as GC-100 status, IR data, relay activation, and reading digital input states. All information, with the exception of serial data, is communicated by comma delimited ACSII text strings terminated by a carriage return (µ).
Serial data is communicated over Ports 4999 and higher. Serial connections with the lowest module number will communicate over Port 4999; serial connections with the next higher module number will communicate over Port 5000; and so on.
 
Commands are always initiated by short ASCII string representing the command type. Typically, address and data information will follow. The structures of GC-100 commands are described in the following sections. Text enclosed in brackets ( <text> ) must be substituted by its ASCII definition. Multiple ASCII choices are divided by separator ( | ) characters. Note: commands are case sensitive.
For example, a relay state is set to ON by the following command:
setstate,<connectoraddress>,<state>µ
where;
<connectoraddress> is 3:2 (3rd module, 2nd relay in module)
<state> is 1 (close contacts on a normally open relay)
For this example the command ASCII string is,
setstate,3:2,1µ
