    Each serial port has a separate telnet port so you can simply telnet
    onto the IOLAN box with an appropriate port number to get to the serial
    line.

    You can also telnet directly onto the IOLAN to configure the serial ports.

    It's worth creating a wrapper script so you can specify the machine name
    rather than the, less memorable, port number.

    These two use the same cable as Netra T1 and quite a few of the other
    low end entry servers.

    For good cabling info see this webpage.

    X1, T1 and Cisco use the same port configuration.
