telnet host [port]
The reason I wrote this telnet program for JavaPad was because I had written a VT100 telnet for the TCL version of pad(Pad++). That was much more hoary project because it involved some strange optimizations. The straight forward TCL program is slow as molasses so I pulled out every trick in the book to get it running at a decent speed.
If you want to run the Pad++ Telnet download Pad++ and click on the menu in the upper right and select telnet. This only works in the unix version, but you can run Linux on just about anything these days so that shouldn't be a problem.
