     Well, Kermit 3.87 works by remapping control-J to the VT100 down arrow,
control-K to up arrow, etc.  This is because those keys are the same as arrow
keys.  That is, pressing control-K will normally have the same effect as
pressing up arrow.  ProTERM was designed to allow as many keys to be emulated
as possible.  That is, with VT100 arrows active in Kermit 3.87, you can never
generate a control-K, control-J, or control-U.  ProTERM requires the option
key down so you can generate the arrows as well as the control characters.

     On the Apple IIgs, it's a different story.  ProTERM recognizes that an
Apple IIgs has the ability to remap the arrow keys.  Thus, ProTERM simply
remaps the arrow keys to the escape sequences and frees up the control
characters.  The reason this works on a GS is that the arrow keys and keypad
are wired separately from the main keyboard.  I don't know if Zlink takes this
in to account or not.
