Another option is midpssh which is a java based solution. The info/download can be found at
http://www.xk72.com/midpssh/ . Unfortunately in the the "type" mode (each key press sent to server) the enter button does not work. You'll have to settle for the "input" mode (type command string locally then send to server by pressing enter). A benefit of this mode is that # keys are bound to special keys like esc, alt, ctrl, enter, ect. Once you memorize the key bindings its a very capable ssh client. In regard I perceive it to be faster than putty or zaTelnet.
