I have a Linux computer (Ubuntu 20.04.5) and a Harman Kardon AVR51 A/V receiver which has a 3.5mm input jack for IR remote control.

My question is, if it is possible to send some kind of command from a USB port on that computer so the receiver for example turn on/off.

I've tried to Google it but from my searching no one tried this before. My idea is to use a USB to serial port adapter and send the data this way.

So in a short way, my goal is to control the AVR51 receiver from computer through cable.

LIRC is software for sending and receiving IR commands on Linux. If you check the "Supported Hardware" section on the side bar of the site, there are a lot of options for transmitters from homebrew LED on serial ports to commercial products.

LIRC should also know what commands can be sent to your AV receiver.
