I try to configure a WLC4402 new out of the box. If I make a console connection for initial configuration I see the boot sequence in my terminal software but I am not able to send keyboard commands. the session does not accept keyboard input. I tried to do this with different PC's, different serial ports and different cables, including the supplied console cable. I have been testing with other devices (cisco router on console cable) and with these devices everything works fine. Only the WLC4402 gives me trouble. Any advice? Thank you.
