I use a serial console (sio0 flag 0x10, /boot/loader.conf console="comconsole", /boot.config -h, /etc/make.conf BOOT_COMCONSOLE_SPEED=115200), but I suddenly have need to quit doing that that and to use that line for a serial output device at 9600 baud. I am trying to do this without a reboot. Is this possible? I have tried using Screen to grab console output into a window so it isn't routed to the serial line, and setting baud rates on /dev/tty*0 devices, * being d, id, ld, ua (always "device busy"), ala, and aia. I can get speeds to change on initial-state and lock-state devices but not on callin/out devices, and as indicated, I can't seem to free cuaa0. The device I want to connect is an output-only (computer --> device) item; namely, a text-to-speech device. Am I missing something, or is this one of those happily few occasions where one really must reboot the OS? -- Doug Lee dgl@dlee.org SSB + BART Group doug.lee@ssbbartgroup.com http://www.ssbbartgroup.com "While they were saying among themselves it cannot be done, it was done." --Helen Keller
