I wouldn't try to set set tty com0 in my /boot.conf, as it does not even work from boot prompt : I wouldn't like to have my computer stuck at boot, without beeing able to get OpenBSD up (seems like my computer does not continue booting after switching to the serial console).
However, good news, I got to make it work, I don't know how, and I don't know why. I discovered this after plugging my only screen for both the server and the windows, on the windows ; I saw console output from the previous boot. However, I don't remember the settings, and I can't get it to work anymore :( I think some unplug/replug of serial cable was involved.
