I've connected a USB>Serial cable to the Rutx09. I've attached a Cisco switch to the serial connector. I can access the Cisco switch over the network by telnetting to the configured port. But when I issue a carriage return, I get the prompt twice instead of once. When I enter "show running" it displays the config, until the screen/pager is filled and stops (like someone pressed "q" instead of "space"). I've played with the "Echo" and "No loading zeros" settings, but they don't seem to be of any influence. Any ideas how to get a "normal" working serial connection?
