Since we're posting annecdotes, I feel I should mention that I've used "device sio" on a modem box used for remote-access serial terminal connections for several years (FreeBSD-5 and FreeBSD-6) without any trouble. No crashes, no complaints, no lockups. The machine is a Dell Optiplex gx260 machine with an attatched US Robotocs modem. The machine serves a few other network-related tasks as well and has performed flawlessly. Right now, the machine currently runs 6.2-Prerelease from a few days ago.
