Yes. I use such a setup on one "server". You need to add the appropriate /dev/ttyUx in your /etc/ttys and ensure ttyflags(8) runs after the device attaches. I haven't automated this on the one box; hotplugd(8) may be the tool for this task. > * Does uscom(4) make this any easier/is it more compatible than ucom(4)? > * If I buy a random USB-to-serial dongle, is it likely that it'll work > with either uscom(4) or ucom(4)?

I purchased all of them blindly, at different times, and all of them happen to "just work". One I have handy right now shows up as: uplcom0 at uhub0 port 1 "Prolific Technology Inc. USB-Serial Controller D" rev 1.10/4.00 addr 3 ucom0 at uplcom0 Another as: uftdi0 at uhub1 port 5 "FTDI usb serial controler" rev 1.10/4.00 addr 2 ucom0 at uftdi0 portno 1. I don't think I paid anything more than $12USD for each. --patrick > Thanks for any input > > regards, > ropers
