It sounds like ProCom is correctly emulating a Wyse 50. The wy50's
attribute handling is just about unusable for a program like Lynx. It
can only display one attribute on a screen, unless the program is
willing to put up with "magic cookies". These are special non-displayed
characters which cause an attribute change, but also take up a character
cell on the display. It is possible to display:
Normal Inverse Bright
on a Wyse 50, but impossible to display:
NormalInverseBright
if each word displays the named attribute.

The Wyse 50's arrow keys send Left=^H, Right=^L, Up=^K, Down=^J. Most
of those keys have special meanings other than "arrow" to Lynx. (I'm
not sure why Tab would fail, though. What if you hit ^I?)

Yes.

Your best bet is to not use a Wyse 50! Your comm software has other,
far better emulations; use them. If you're doing this because you have
a warehouse of real Wyse 50's to bring online, look in their setup
menus. Maybe real Wyse 50's know how to emulate something usable.
