i've been using usb-to-serial adapters to deal with equipment such as serial-console openbsd boxes and cisco devices. i'd like to move toward something like the digi or perle console servers.
i used the digi equipment over a decade ago with both hpux and aix with success. i'd really like to access these from my openbsd workstation and laptop, though the documentation mentions support for just about everything other than bsd. are any of these usable with bsd? and by that i mean can openbsd connect to the serial ports via ethernet with cu or something similar?
