I just looked at a 2.8.5dev.8 that I compiled with slang with DJGPP.
I don't have FANCY_CURSES defined, nor USE_MOUSE. I thought that
USE_MOUSE was in lynx.cfg rather than a CFLAG, and last time I checked
slang didn't support mouse under DOS. Has this changed? It looks like
your "while" condition is the same as is used in "kbhit", so it ought
to apply when there is no keypress.

I don't understand how you got FANCY_CURSES defined when using slang?
Which options did you use when you ran "configure"? I don't know if any
of this applies to your question about tcp_tick being called, but it
looks unusual. How do I tell if tcp_tick is being called?

This is the set of options I used to configure lynx for slang under
DJGPP:
