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). My problem is that I've got a Wyse WY75. It has an "enhance attribute mode" which is magic cookie free. However, all chars on the screen written with enhance on have to be the same attribute - dim, inverse, or underline. SGR (\E[p0;p1...m) simply turns enhance on or off - only the last param is effective, 0 being enhance off, >0 on. So, I've got standout set to use the enhance mode. Wyse also includes a WYFDAT (`field attribute') which gives you the 32 combinations of dim, blink, blank, underline, and inverse. However, this uses a magic cookie. I use this for underline, and the appropriate atrributes. I can give "ug" for the underline magic cookie, but not for the others! BTW, `more' in 4.3 correctly uses so/se/sg and us/ue/ug. `ul' uses just so/se, us/ue, plus the other attributes, but it mucks up badly because of the lack of handling of magic cookies (sg/ug). *sigh* -- John LoVerso, Encore Computer Corp encore!loverso, loverso@multimax.arpa (XXX)

(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_. -- Brandon S.
