One of these software solutions may be just what you need to help you create virtual COM ports.
Virtual Serial Port Driver is a software package developed by Eltima Software that functions as a virtual COM port emulator on Windows machines.
However, this tutorial will describe how to "clean" COM ports that are in use, and how to disable numbering of new ports.
Recently, I bought a Prolific USB-to-Serial adapter for flashing my Android smartphone that I had accidentally bricked.
Even when you turn off the device, the COM port that is assigned to the device remains reserved for it. Navigate through folders: HKEY_LOCAL_MACHINE\SYSTEM\Current Constrol Set\Control\COM Name Arbiter 3. Check those ports after Windows assignes them a COM port, there should be written " regedit then click Enter. Navigate through folders: HKEY_LOCAL_MACHINE\SYSTEM\Current Constrol Set\Control\usbflags 3. Repeat step 3., and name new file as Ignore HWSer Num04036010.
That is, each time you reconnect they will be assigned to the same COM port. The problem can occur if some software that comes into your device is set so that it can access only, say, the first five COM ports. Right click on folder usbflags, zatim New - Binary Value 4.
Some machines take it a step further and do not have ports of any type, relying on wireless connectivity to peripheral devices.
The reduction in reliance on COM ports in machines and devices used for general purposes has not eliminated the requirement for serial connectivity.
This can be problematic with current computers as there may not be serial ports available on the machine.
Serial port emulation might be just the answer you are looking for if you in this kind of situation.
