Creating a Virtual Serial Port in VB.net

**ThunderStick** · 11-24-2009, 07:12 PM

Im trying to create a virtual serial port in VB.net
I know how to open, recieve and send data using the serialport control.
But I do not know how to create a Virtual Serial port so I can use this for data output or for splitting other ports.
I searched all over google for an example but couldnt find anything that was usefull. Most want to sell you a control or API, not interested in that. I just need a starting point and I can figure it out from there.
Any help is greatly appreciated.

Curiosity's your man, he wrote Xport which basically does that.

You have two options: download com0com, or write something in a lower language than VB

http://com0com.sourceforge.net/

I'm using com0com to hook up obdsim to other OBDII software on windows. It's open-source, and so far has been absolutely fantastic for my needs.

I had to google for a while to find xport. "Xport" finds nothing of use at all - eventually it seems that searching for "xport compass" will produce the top link in google that you want. "Xport curiosity" doesn't even find the right page except a bunch of links to mp3car.com

So, I guess, "in future, when you suggest xport to someone, provide a link to the xport download page", because it's hard to find

theres two API calls that allow you to do this...if you can't find them i can look them up tomorrow but thats the direction you wanna be looking in.

I think its codeplex that has a good writeup but I could be off, google around for it done in any language and see if you can find a reference to the api calls.

Not if you search the memberlist here for Curiosity and look at his profile/signature

"XPort GPS" works pretty good on google.

XPort is a great tool, and I have been using it for years. But I am creating an all in one solution and need a virtual comport created with in the same application so that it can output data in the form of a string to this virtual serial port.

Oh yeah, and done in Visual Basic .Net
using the 2008 Express edition...
Possible or should I give up... I don't like to give up..

"XPort GPS" works pretty good on google.

And now you mention it, "xport virtual serial" works too. I just get grumpy whenever I type something into google and it doesn't show up first time - in this case, enforcer said to look for Xport, which I failed to find.
