how to do / test RS232 communication to control surround receiver

Hello community,

I hope someone can help me out here.

According to LibreElec + other Linux stuff installed - General Support - LibreELEC Forum, I cannot install any Linux serial console programs mentioned How To Check and Use Serial Ports Under Linux - nixCraft.

How can I check if the host itself (LibreELEC on Pi 4) would be able to control my surround receiver via RS232 using

LibreELEC:~ # dmesg | grep "usb 1-1.4"
[    2.243577] usb 1-1.4: new full-speed USB device number 3 using xhci_hcd
[    2.349783] usb 1-1.4: New USB device found, idVendor=0403, idProduct=6001, bcdDevice= 6.00
[    2.349797] usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[    2.349808] usb 1-1.4: Product: FT232R USB UART
[    2.349819] usb 1-1.4: Manufacturer: FTDI
[    2.349829] usb 1-1.4: SerialNumber: A10K5SV4
[    5.173412] usb 1-1.4: Detected FT232RL
[    5.185287] usb 1-1.4: FTDI USB Serial Device converter now attached to ttyUSB0

Could LIRC an option?

According to LIRC - FTDI driver --> FTDI USB driver the chip itself is supported.

Holà, that was quick😃

although I'm lucky, my rotel does use default settings as screen seems not to support all possible parameters and stty is not available.
