I've been poking around at system docs this morning. I'm already using the After=system-udev-settle.service and Wants=system-udev-settle.service that you recommended last week, Dave. Makes sense: I don't want brltty to start until the console interrupt is available and until after udev isn't going to mess with my serial port's communication parameters.
Clearly, as we discussed on Friday, that's not what's happening. I'm getting the error when brltty tries to get console control, and the baud rate, as reported by sty, is changing back to 9600. I'm happy to have brltty start later so that, when it starts, it actually has access to what it needs and that things keep working, obviously. Any thoughts why the system-udev-settle service isn't doing the trick? And what might? FWIW, I added these additional wants and after lines to brltty.service rather than the [email protected] abstract service unit definition. Was that the right place to put them?

Yes, serial port probing messing up a port's settings isn't anything brltty can do much about. Waiting for udev to settle, though, is, in my opinion, the right way to deal with it. Maybe there's a way to tell udev (or maybe it's the kernel) not to probe for modems. That probe is a bit annoying, especially when, these days, few people actually have them. >Only the console interrupt issue is something I'll await a fix for from you >all. Fixing that isn't even, strictly speaking, necessary since, again, waiting for udev to settle resolves it and is the right thing to do. Nevertheless, I do still intend to fix it because it indeed is something brltty can (and, therefore, should) deal with. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
