1. Why did terminal manufactures go with magic cookies?  The magic cookies
   make display attributes useless.

2. In working with TVI910, TVI912c, and HP700/41 terminals, I've tried
   playing around with the terminfo (HP/UX) magic cookie glitch settings and 
   haven't been able to work around the problem.

   I haven't been able to get rid of the magic cookies when using Esc
   codes in local mode either.  The picture on the TVI manuals show a nice 
   data entry screen using all the display attributes, but I see no 
   possible way to make that data entry screen, how did they do it?
