The telnet control interface is considered deprecated. Roku replaced it with ECP (the External Control Protocol). Using ECP, you can send a launch command with the appid of the channel you want to launch, e.g.
http://192.168.20.111:8060/launch/11will launch the channel store. App ids can be obtained from several sources: through ecp, using the 'query/apps' command, from the developer control panel (for channels you've developed yourself), or from the Roku channel guide website (they're part of the URL, when you are looking at a channel's details, e.g.
http://www.roku.com/channels#!details/12/netflix <- the appid is 12).
Here's the documentation for ECP:
