The scoop is (I think as > follows): [ useful informative table deleted ] Can anyone tell me if the line drawing characters are standardised in any ISO standard? I mean the kinds of characters you use for drawing boxes on terminals, e.g. like the ones that really annoy you when your VT100 has received some line noise :-) Email would be appreciated. If the info is forthcoming, I will summarise (to std.internat). Thank you. -- ronald@robobar.co.uk +44 81 991 1142 (O) +44 71 229 7741 (H)

I don't know if it is aligned with a corresponding ISO standard, but CCITT Recommendation T.101 defines several registered character repertoires which contain line drawing and mosaic characters (notably, ther Data Syntax I, II, and III character sets). The documents that describe these are: CCITT Recommendation T.101 CCITT Recommendation T.101 Annex B Data Syntax I CCITT Recommendation T.101 Annex C Data Syntax II CCITT Recommendation T.101 Annex D Data Syntax III CCITT Rec. T.51 Annex B has a table of the ISO registered character set selectors for the character sets used by T.101 (and some others). T.101 was aimed at applications such as Videotex, and so it uses a much richer set of figure-drawing characters and primitives than something like the VT100. -- Amanda Walker amanda@visix.com Visix Software Inc. ...!uunet!visix!amanda -- "I can only assume this is not the first-class compartment." --The Hitchhiker's Guide to the Galaxy
