Hey y'all. I'd like to set up a serial console terminal server for my home lab. I am aware of the ser2net solutions, but that requires a $10 USB dongle for each console plus USB hub. I see that the Pi 4 has six UARTs on its GPIO. What problems will I run into using those directly? Bonus: I ultimately want to have about a dozen serial consoles. Are there suitable UART expansions available? TIA
