I am doing a project in modbus, i framed the request for reading coils in TCP,but i dont know how to do it for serialport can anyone help to frame this.
It seems you're using C#. In this case, I suggest you to use the nmodbus library.
It's open source and allows you to perform any Modbus operation via both TCP and serial protocol.

I'm using C# to command a GSM/GPRS modem via a serial port.
Can I write the commands to the port one after another without a gap or should I wait for the response form the modem after the last command? Using something like Thread.Sleep.
I use it to send SMS to multiple phone numbers.

How to show and block ip UDP incoming in c# WinForms.
Show ip and incoming packet in label like Anti DDOS Guardian
I made a similar application some years ago using WinpkFilter. I don't know if there is something better, but this gives you all that need to read all packets passing on network interface. Once you read the packets, you can check protocol type and make all operation you need to prevent DDOS.
You have to install the WinpkFilter driver and link the ndisapi.dll library, I suggest you to give it a try and see if this can help you.

How to send/receive a HTTP request (it is good to give me a link)
http://msdn.microsoft.com/en-us/library/debx8sh9.aspx
Do you know what i typed into Google?
"c# .net send web request"
And this was the first result.
The simplest option is the System.Net.WebClient class, but that isn't always powerful enough to do what you need.
