Except it is not a telecom equipment 40 years ago. Even at 115200 that I routinely use on my development systems I feel serial console output affects verbose boot time and kernel console debugging output. I also have BIOS console redirection enabled on my systems, and I believe the default there is also 115200, and even that is pretty slow. I see no point to stay compatible if it is unusable. -- Alexander Motin
