I have been holding off from responding to this thread because I developed
Telnet/400 and I don't want to appear that I am promoting it. However, I can
explain what is causing the "sluggishness" that you are talking about.
Telnet/400 uses the VT100 protocol which means each keystroke is sent to the
AS/400 and is not displayed until it is echoed back to the PC. Depending on
the speed of the line it may appear slower when keying data, although I
haven't noticed a significant difference. However, it does greatly simplify
the programming and results in a very small program. 

This was my goal in developing Telnet/400. I wanted a program which would be
easy to install and use and provide basic terminal emulation for the AS/400.
It was never intended to be a full function emulator like Client Access and
may not be suitable for everybody.
