COM Port settings

[Ashish]

Hello,

I have a display device connected to the USB port of my
computer. The COM port number of this device is 10. I want
to change the COM port number of this device to 3 or 4.
I am unable to change the COM port number of this device
as the port settings tab for this device is not available.
I can go to the device manager and change the COM port
numbers of all the devices using the port settings tab but
I am unable to do so for this display device as the port
settings tab is not available.

I tried to change the port number by modifying the
registry but when I re-boot the machine the COM port is
again changed to the old value.

I have been trying to search about it on the web but not
able to find it. Please let me know if anyone came across
the same problem and what is the solution.

Thanks in advance,
Ashish

Not possible in my amateur opinion. A call to the maker of the device
will tell for sure tho.

If I uninstall and re-install the drivers. It increases
the COM port number. If the COM port number was 10 and
then I re-install the driver it becomes 11.

It is possible to change the COM port numbers by going to
the device manager and selecting the properties of the
device. I am able to change the COM port numbers of all
the device and not this one.

Thanks,
Ashish

Plug And Pray, you're not Praying enough

You will need to get in touch with the manufacturer of the add-on USB
serial adapter that you have to see if they have any type of utility
that would allow you to either set or remap the COM port number that
is assigned to your add-on adapter.

If they do not have anything then the only other alternative would be
to use a third party tool.

My company sells a product called TCPCom that is primarily designed to
expose a physical RS232 serial port to a TCP/IP port either as a
TCP/IP server or as a client however the program also has the ability
to create "virtual COM ports" using any COM port number that you like.
You can also run multiple sessions in TCPCom so you could configure
one session as a TCP/IP server opening up your COM10 port and then
open another session as a TCP/IP client that connects to the server
session and also have the client create a Virtual COM3.
This effectively allows you to "remap" your COM10 to COM3.
You can download a demo version of TCPCom from
