How can I share a virtual COM port over WiFi or similar network link with other PCs? I have a Hardware dongle connected the USB on my main PC and would like to simply replicate the Com port.
You can share a physical or virtual COM port with the help of an application. For example, I have found one called Advanced Virtual COM Port which is capable of sharing all the COM ports available on your PC.
You can get an overview about this using the following link: http://www.advancedvirtualcomport.com/productoverview.html
There is also a page where you can see the sharing procedure: http://www.advancedvirtualcomport.com/advancedvirtualcomport-help/howto-share-physical.htm
