If I rearrange the letters, does this form a question? Is it a cryptic crossword clue? If so, you forgot to say how many letters the answer is.

Hi can we make virtual com port using c# .net?
If then how?
I don't want to use any third party tools
If anyone knows it please reply soon..

Thanks in advance.

yes you can,
of course by writing code in visual studio,
maybe this will help you. Smile | :)

Errm, no you can't. You can't write a driver in C#.

I don't know about that. You MIGHT be able to do it, though it would be far easier to just learn C and write the driver that way.

Hmmm, recoding all the enums, structures, P/Invoking the crap out of all the necessary functions, adding the entire weight of the .NET Framework to the Kernel, ... Nope, I don't see a problem with that at all! Wink | ;)

The problem is, unless you were to statically link everything in to your code, you can't get the .NET framework runtime into ring0.

I was mostly joking around. Even if it did work, the amount of work required to recreate the "framework" required to get a managed driver FAR exceeds the amount of work to learn C, IMHO.

As you'd need to create a driver to do this, you can't accomplish this in C#. The reason that this is the case is that you can't have the managed runtime running safely in ring0. You can't even run in User Mode Driver Framework to achieve this.

Umm Silly answer but have you tried looking for a USB to Serial Driver on the web,
two main types Prolific & FTDI (I questioned Pete yesterday on how to get the details of an FTDI driver) any way installed the driver, plug the device in to the USB port, cross your fingers (not needed but recommended!) look in Device Manger under the Ports option (it may also appear in pop up balloon on the desktop temporarily) as a COM number say COM6
then open COM6 and talk to it with a terminal emulator, Hyper-terminal is not great for this but will do, important to note Hyper-terminal (free version at least) will crash as it does not handle virtual serial ports properly.
When you say you don't want to third party tools is due to copyright restrictions or safety reasons (Prolific & FTDI are tested and can be used as part of an assembly have a look at the restrictions on the web site)

i'm not sure how to help, but you can check this link, guess number two is what you need.

They are in the wardrobe, in the attic. There, we've found the photos. You can put your feet up, safe and secure that you know exactly where they are.

But wait. Have you actually checked they are there? Go ahead, I'll wait.

They are? Good.

I looked, but they aren't in my attic. I think your algorithm needs a little tweaking.

I looked in the wardrobe but all I found was some strange looking guy with goat legs that went on and on about some witch and how cold it was. He didn't seem to know anything about pictures.
