I have a 2511 that I use in my lab as a terminal server. Connections work great, except using the command "clear line x" does not always clear the connections. I enter the command "clear line 1" and press enter. I get the [confirm] message. I press enter. Doing a show line still shows the line as being tied up (indicated by an asterisk). I can repeat the clear line command several times with no changes. Its not all the lines, only some of them. (I have 2xoctal cables being used with 16 devices). Thoughts?
