Interesting "feature" of older model 2501 console connection

Discussion in 'Cisco' started by Bob by The Bay, Jul 24, 2003.

  1. My oldest 2501 requires a null modem with no handshake adapter on one end of
    the console (flat rolled) cable for my terminal session keystrokes to be
    heard. It displays console output onto the terminal session OK with just
    the flat rolled cable/9 pin terminal adapter, but unless I use the null
    modem adapter, my keystrokes aren't heard on this particular router.

    None of my other 2500 series routers require anything more than the rolled
    cable to 9-pin terminal adapter for both display and keystrokes.

    I remember a time when the null modem without handshake was a popular access
    method with other gear, but this seems a little funky.

    I just wondered if anyone else has experienced this "feature" with any of
    the older model routers?

    Anyone know if there is a jumper or bit setting in firmware that alters this
    behavior?
    Thanks in advance!
