These three components seem to set their console speed > in some cases arbitrarly. Yes this seems to be the case. No matter how hard I try to convince sio.c to default to 57600 (I even went as far at setting static volatile speed_t comdefaultrate = CONSPEED; to 57600) so there would be no confusion. I still end up with random console speed each time. The boot loader did pick up the speed from /etc/make.conf and does come up every time at 57600. > > In my kernel I have the CONSPEED and the BOOT_COMCONSOLE_SPEED > in make.conf set accordingly. > > Anyway its not a big problem for me now any more, so I never > filed a PR. > > Best regards, > Daniel -- Russell Cattelan <cattelan@thebarn.com>
