Now to the real question again, because I'm a little confused now - can I still get a usb-to-serial port converter having let's say 8 serial ports and then connect each machine to the usb-to-serial hub and manage them remotely from a single location (the host having the usb-to-serial hub)? That way I just specify a serial port number and I get to a specific machine? The model provided by Boris looks nice, and that was my initial idea, but I'm not sure if I could get it working under FreeBSD. Is conserver or conserver-com able to handle this? I know that cu uses COM1 only, but will conserver able to handle serial consoles on different ports, since the usb-to-serial port would appear as multiple serial ports.
