Hi, I have put an RS232 interface on to one of my MBWEs so that I can attach my LaCrosse weather station to it.
The interface seems to work fine, and I can communicate with my weather station quite well.
I commented out the getty line in /etc/inittab for /dev/ttyS0, so I don't get any login messages, but I'm concerned that the next reboot will see all the console stuff being offered up to my weather station's serial port. I'd rather avoid that if it's possible.
Since there's no /boot directory on the MBWE, I'm starting to think that the configuration that I need to change is somewhere in the startup ROM.
Can anyone here confirm or deny this for me? If there is some accessible configuration, I'd appreciate knowing where it is…
