telnet blank screen

When I telnet to port 110 from local or internet addresses I get a blank screen with a blinking cursor. It appears to be connected. However, my pop3 service will not connect. It seems I have a bunch of people connecting to this pop3 port and I do not know who they are. Has something taken over my port?
Help...

Who is Participating?
I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

OK, so what changed? something has to be different for it to stop working, maybe a change that didn't take effect until a reboot of server or PIX?
