Is serial communication possible in .NET

[mahvk]

Hello All,

I was just searching for classes for communicating with
the COM port. But I can't find any such classes/methods in the
.NET framework other than the API functions.

And also I am not sure how to make use of these API functions
in my .NET application.
For example one of the API function, CreateFile has
LPSECURITY_ATTRIBUTES structure as one of the parameter, how
I can declare/use this particular method in my .NET application.

Can you please help me out !!!

Regards,

I am not sure whether the regular API functions are not any longer available or you just did not find them...

Depending on what you are trying to do take a look at the functions

BuildCommDCB()
ClearCommError()
CreateFile()
EscapeCommFunction()
GetCommModemStatus()
GetCommState()
GetCommTimeouts()
GetOverlappedResult()
ReadFile()
SetCommMask()
SetCommTimeouts()
WaitCommEvent()
WriteFile()

Additionally, the MSDN (http://msdn.microsoft.com) provides a detailed article about serial communication in Windows. Open MSDN, choose Index and type "Serial Communications". There are several subitems, choose 'Win32'... (it's also online available at http://msdn.microsoft.com/ library/d...s/dnwbgen/html/ msdn_serial.asp).

You probably might wanna take a look at http://msdn.microsoft.com/library/d...tm/serial_7.asp...

Well...if you include the appropriate header file and the libraries which are stated within the MSDN there should not be any problems...

I afraid, there is no class to manipulate COM port in .net framework.

You have two choices:
1.) Import all function you need to work with COM port to the .net application. (DllImport()...)

2.) Write COM object in C++ that will allow you to use COM port and use that COM object from you .net application

Hello All,

I am able to make use of APIs to communicate with the serial port.
It works pretty fine.

Thanks a ton to everyone.

There is a nice sample present on MSDN on how to communicate with COM Ports. Take a look at Using the COM Port in VB.NET (http://www.microsoft.com/downloads/details.aspx?FamilyID=075318ca-e4f1-4846-912c-b4ed37a1578b&displaylang=en).

Download this sample and it contains all the APIs and their implementation in .NET.

Hi

I got my C# app running in 10 minutes with the following serial communications approach:
