Windows 10: Clashing devices on serial COM ports

I am using a Windows 10 Enterprise x64 PC. I have an Adafruit Feather M0 Express board and a Kortek touchscreen. I can use either of these devices individually on the PC. They work over serial communications. However, when I install the drivers for the touchscreen, the Feather board stops working completely. It seems that when the touchscreen drivers are installed, it causes a conflict and the touchscreen takes over.


Why can this happen? What is the workaround for it?

Changing the Port settings for Serial-USB.

Hi,



Thank you for writing to Microsoft Community Forums.

If you want to change the port settings, please follow the steps mentioned below:

1. Open Device manager (right click on start button
   and then on Device manager).
   
2. Then expand port (COMS & LPT).
   
3. Then right click on Prolific USB-to Serial Comm Port and then on properties.
   
4. Go to port settings and click on Advanced.
   
5. You will be able to make the changes on this screen.
   

Hope this helps.

 

Serial port connections are not detected, and COM port option is not showing in Device Manager.

Com port as in Serial port or parallel port

Plug n play or legacy ports?

There should already be drivers loaded in device manager

Use the add hardware wizard and install the port from the list and restart PC.

 

How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".
