As quoted from <1894@encore.UUCP> by loverso@encore.UUCP (John LoVerso):
+---------------
| Can someone in-the-know tell me why magic-cookie glitches are not fully
| described in either termcap or terminfo?  Termcap lets you specify
| a magic cookie for standout or underline (sg,ug); terminfo only
| has a capability for one magic cookie value (xmc).  Neither try to
| describe cookies on attributes (blink, bold, dim, invis, rev).
+---------------

Wyse terminals are properly described as "even more braindamaged than
Televideos".  (You want _real_ brain damage?  I have a Teleray 1061!
You have two options for attributes:  _asymmetrical_ invisible magic
cookies, or symmetrical but visible (dual parallel vertical bars) ones.
The standard termcap uses invisible attributes and fixes the asymmetry
by including an extra space at appropriate points and setting sg#2!!!)

Wyse has other problems.  I can hang a Wyse 50 to the point that the power has
to be cycled to fix it by sending it VT100 control codes.  (Happened a lot at
TDI:  they have both, and move them around periodically.  And no reason for it
in the control codes; <ESC> [ is a cursor position command.)  I have yet to
see a Wyse terminal with the yoke on straight (the text looks like the Leaning
Tower of Pisa).  The stupid handling of attributes has already been mentioned;
with memory so cheap nowadays, *why* can't they release a terminal which does
attributes right???  After all, it's not as if they don't build new models
constantly -- they sell them to Altos; seen the "Altos V"?  RS422, forsooth!
And of course they had a chance to do it right with the 60, and didn't....

I, personally, will take a cheap PC clone running Procomm over a Wyse
so-called "VT100 compatible" any day.  It's cheaper, and the attributes
are done _right_.
