What could be worse than a Televideo? Perhaps a newer Televideo? One of my customers recently ended up with a couple of Televideo 955 terminals. It really wasn't his fault... They asked me to set it up and write termcap descriptions for them. When I read the manual, I was dumbfounded. I vaguely recalled hearing or reading somewhere that Televideo had finally gotten away from the magic cookie glitch. Well, if this is it, they didn't quite get away from it. The 955 has two attribute modes, which Televideo boldly calls 'embedded' and 'non-embedded'. The embedded mode is just what you expect, attributes have magic cookies, like the 950, did, and the 925, and the 912... But the non-embedded mode has a very long description, which boils down to when you send the set-attribute sequence, something magic happens inside the terminal which allows you to write the next - *only* the next - character on the same screen location you were at when you sent set attribute. After that next character, whatever it was, the terminal reverts to traditional Televideo behavior; if at any later time you write any character to that screen location, you lose the attribute! What could this mode possibly be called? Perhaps, 'magic magic cookie'? Or 'voodoo cookie'? jw

One of >my customers recently ended up with a couple of Televideo 955 terminals. >It really wasn't his fault... It seems that there is more than one ype of TeleVideo 950. I have (frequent) discussions with people who hat them because they are impossible to use. All I can reply with is that the 4 I have used at work and the 2 I have at home have the crispest, most stable display I have seen on a terminal. This leads me to believe that TVI made a significant change in their line at some point. I have a 955 at work now. I do not like the display as much as my old 950 but the larger screen is kind of nice. It took me about an hour to develop a new termcap that worked in 955 native mode. The magic cookie is completely gone in this mode. Given the screen jitter and flashes, I am torn between going back to the 950 and living with magic cookies and staying with the 955. >They asked me to set it up and write termcap descriptions for them.

I would include a termcap but mine is highly customized for a specific curses which has field conflicts with BSD 4.3. /\/\ \/\/ -- Michael R.

televideo 955 that appears to him to always have some flavor of magic
cookies...
You are mistaken. Check out the "attribute: no space" option about
page 4 of the setup screens.
Actually, for a non-ansi terminal I thought it was pretty slick. I
mean, I haven't seen very many $400 terminals that could handle 38,400
baud with no delays or flow control. Certainly not my
almost-as-pretty wyse 60 that needs flow control for 4800 baud. :-)

We have several type of TVI's here, but the best is the TV9220 - it's not compatible with the 950/970 series, but essentially a vt220 without the brain-damaged keyboard. I can send termcap entry and some loadable fonts (Hebrew, anyone?) if anyone is interested. -- Amos Shapir (My other cpu is a NS32532) National Semiconductor (Israel) 6 Maskit st.
