Thanks, Dave. I'll tinker some more on Monday and report back. But this sounds like a system issue and not a brltty 5.4 issue, or at least not something that needs to be coded around. Only the console interrupt issue is something I'll await a fix for from you all.

Is that true? It depends on the device. In general, the driver knows which bauds it's able to use for the models it supports. >Do you know if the Power Braille does auto-detect or if it insists on 19,200? The Power Braille can operate at either 9,600 or 19,200 baud. The driver tries first at 9,600, and then at 19,200. If it works at 9,600, then it tells the device to switch to 19,200, and then uses that. >I'm also open to suggestions how I might go about finding out what's >changing my baud rate.

I know that when I connect a USB to serial adapter, the first thing I observe is a modem probe. My guess is that udev is doing it, but I've never checked to be sure. In any event, you'll notice, in the systemd dependency rules I sent you, that they now wait for udev to settle. That should be sufficient. -- Dave Mielke | 2213 Fox Crescent | The Bible is the very Word of God.
