How to redirect QEMU -serial output to both a file and the terminal or a port?

I would like to be able to both interact with the system via the command line, but also get the output to a file at the same time.



If I do:



qemu-sysem-x86_64 -serial stdio |& tee file


then it mostly works, but I would like to avoid any Bash operations and let QEMU do the heavy lifting for me. For example, I'm using Python, and it is not so simple to implement a reliable tee there.



If I do:



qemu-sysem-x86_64 -serial file:myfile


It redirects to the file and I can't give any input.



Is there a way to "combine" both file: and stdio to a single -serial?



Multiple -serial entries just create multiple serial ports instead of modifying a single one.



I'm also interested if it works with telnet as in:



-serial tcp::1234,server,nowait

          up vote 0 down vote favorite Good day all. I have a window that pops up saying Fatal Program Failure (AnyDesk). This is what I have done so far: Uninstalled AnyDesk and reinstalled it. ( The window still appeared ) I disabled AnyDesk start up in Msconfig and the window seems to have disapeared. Lastly I made sure that AnyDesk worked by remoting into it, and it worked.

          How to calibrate 16:9 built-in touch-screen to a 4:3 resolution?

          Image
          up vote 0 down vote favorite I need help with an issue we're facing in a project where we are moving from a Windows-based POS environment to one running on CentOS7. The problem consists of a number of factors, please find the details below: The supplier of our POS application will only deliver an application that is hard-coded to run in a 1024:768 4:3 format. The hardware we are using is a POS unit from HP that has a built-in 16:9 touch-screen. The employees using this solution is not supposed to see nor have access to anything but the POS application. Our sales organization demands that touch is an available feature when going live with the new POS environment.

          QoS: MAC-Priority for clients behind a repeater

          Image
          1 1 I've setup a wireless network using a Linksys-Router (DD-WRT) as an AP and a TP-Link repeater for range extension. To manage bandwith for specific users, I've setup QoS-Rules on the AP (DD-WRT) using MAC-Priority: However the AP shows only the Repeater's MAC and the MACs of users inside the AP-Range. The MAC addresses of users behind the Repeater are not listed : The purple MAC is not listed in the AP-Clientlist. Its related to a device connected via the TP-Link repeater. Q: How can I setup MAC-Priority for repeater-clients? Do I simply add the purple MAC in AP-MAC priority list although it's not listed as a client? I want to setup specific priority instead of giving one priority for all clients behind the repeater by adding the repeater's MAC in the MAC priority list in the AP as ...
