[ Additional blasts of AGATE omitted ] For the record, none of IBM's code pages* (there are several) are ANSI, even the ones that aren't EBCDIC. Even IBM admits this. The standard code page and escape sequences adopted by ANSI are a subset of the old VT100 code page and escape sequences. That means that to be ANSI compliant, it need not understand any of IBM's special characters or escape sequences (which change colors, etc.). >A friend of mine, however, is currently working on a IIgs specific ANSI program.I've seen the beta version, and it really is impressive.. all the IBM >characters, color.. and all. [ Implementation details omitted ] No, he's not writing a program that understands ANSI. He's writing a program that understands one of IBM's many code pages and some set of escape sequences. By the way, IBM's code pages on the PC and its clones and decendants have changed over the years. I think your friend will find that if he connects to a PC, he'll see subtle differences in the characters as compared to the XT, AT, RT, PS/2, and clones. >Lyle * By the way, "code page" is (according to IBM's National Language Support Centre in Toronto) the mapping between a character set (e.g. "0123ABCdef" and so on) and the way the implementation represents it. Any ASCII chart is one such code page. Disclaimer: I've never used AGATE. -- Paul Sander (408) 734-9822 | Wisdom is beyond price, my son.

It is more of a subset of ANSI. When I messed with using vt100 on an ansi ibm bbs, the only problem I came accross is the save/restore cursor codes are different. And the bbs I'm thinking of, used them often, probibly because of the way it stored its graphic images. >>If you run AGATE, and call a IBM board, any color code will screw up After reading the first message of this thread, I downloaded agate to see what it was like. It uses double hi-res, black and white mode for its display. It took me awhile to find apple-4 sets 2400 bps. I never did find keys to set parity. So if you call somewhere that uses parity, better not count on a readable display. A local bbs has a multi-color graphic and agate handled it without any problems, except for not seeing color. It did filter out the color commands for me. As far as speed goes, it does keep up with 2400 nicely.

I have a communication program I wrote that I would like to add the extra codes in. I hope to convert this program to a cda sometime this summer before I let it loose on everyone. Currently it's a prodos 8 application. >By the way, IBM's code pages on the PC and its clones and decendants have >changed over the years.

Certain graphic characters change slightly or change a lot? What do I need to watch out for?

Hmm.. never knew that those IBM characters weren't ANSI.. but.. it has been used interchangably on almost all IBM BBS's.. so.. So, then.. what IS the ANSI standard? But.. going back to the original subject, AGATE is not worth the trouble.. it does not achieve anything ProTERM or another term program with VT-100 can achieve.. does have some ANSI characters, but only a small sub-set of them.

In-Reply-To: message from paul@athertn.Atherton.COM I think what he was referring to was the 'adopted ANSI standard' used by most IBM bullitin boards. ---------------------------- | mquinn@pro-gsplus.cts.com | | Aritst GS+ Magazine | ----------------------------
