Windows Telnet Client Tool Needed

I need a windows form application, that will automate several Telnet commands for a Cisco router. I will provide the commands and expected responses. The app will be a single screen, with 4 or 5 buttons each that issues the various commands. It will have 3 or 4 user input fields, like IP address, username and password. I would like the code in either C# or VB.Net
