Since these switches have a tendency to lock up despite my best efforts and every suggestion on this forum, (though curiously I have never had the console lock up) I would like to connect an external modem to the switch's console port so that I can reboot the switches when I cannot contact them in-band. So far I have had no luck getting this to work beyond the external modem answering and handshaking with my laptop modem. Does anyone here have any init strings/suggestions/advice? I'm using a USRobotics Sportster 33.6 external, specifically it is model 000839-09. Also, should I be using a standard modem serial cable between the modem and the console port on the switch, or a null-modem cable (which sounds counter-intuitive, but which I am willing to try since nothing else seems to work). Also, the modems are known to be good, I used to use them for remote management of some SCO Unix boxes. Thanks in advance.
