KB5039211 breaks my ability to print to my com port Roland engraver

I have a Roland EGX-30 engraver connected to my Windows 10 22H2 PC via a serial com port.

I use Dr. Engrave 2.72 to design and print to the engraver.

After applying KB5039211 (June 2024 cumulative update) it no longer works. All of the hardware shows to be ok in the device manager.

If I uninstall KB5039211 it starts working again.

Any chance this is a known issue that will be addressed in next update?

Thanks

Hello,

Thank you for reaching out. My name is Gyula H., and I'm a community expert here to assist you with your issue. I understand that after applying the KB5039211 update, your Roland EGX-30 engraver connected via a serial COM port no longer works, and uninstalling the update restores functionality. Let's work together to resolve this issue step by step.

Step-by-Step Troubleshooting

We'll start with a basic step to try to resolve the issue without uninstalling the update.

Step 1: Reinstall the Serial Port Driver

Reinstall the Serial Port Driver:

Press Win + X and select Device Manager.

Expand the Ports (COM & LPT) section.

Right-click on the serial port connected to your engraver and select Uninstall device.

After uninstalling, restart your PC. Windows should automatically reinstall the driver.

Please try reinstalling the serial port driver and then test if the engraver works. Let me know if this resolves the issue. If not, we'll move on to the next step.

Best regards,

Gyula H.

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".
