Arrow Keys (was: ptse terminal for Unix?)

[John David Duncan <jdd@darkwing.uoregon.edu>]

I'm stuck in what feels like a stupid problem.

First, I noticed that when I used Pine and Lynx from the VT-320 Terminals 
at the university, I had fully-functioning arrow keys.  Trying to use 
Lynx from home, with ProTerm 3.0 at 8N1 emulating a VT100, the arrow keys 
would NOT function.  (Using Lynx without arrow keys is a pretty limited and 
frustrating endeavor). 

I remembered that when I had called a ProLine BBS and enabled ProTerm 
Special Emulation, one of the neat effects was that the arrow keys were 
fully functional.  So I posted my message to this newsgroup soliciting 
a termcap/terminfo file for Proterm Special that I could install on my 
unix account.  

Ron Higgins posted a terminfo file here, I pestered my sys admins to 
compile it and get it into the right directory, then I logged on, set my 
terminal emulation (both on unix and on proterm), and the result:
no different from VT-100 emulation. Boldfacing and screen positioning 
worked fine, but no arrow keys.  The down arrow translated as a newline
(Return), and up, left, and right were "unrecognized commands," just as 
before.  

What's going wrong here?? What could the problem be??
