At present, PuTTY's default response to DA (CSI c) is CSI ? 6 c, which

denotes a VT102.  This is slightly inconsistent with xterm, which returns

CSI ? 1 ; 2 c -- a VT100 with AVO.  Since PuTTY supports quite a few VT400

options, I suspect it would be more sensible for it to return something

in the 6x range, perhaps based on the current compatibility level set

by DECSCL.  Maybe it should even be configurable -- it is on a VT420.



We've had a report of this causing problems with entry of greek text, and

a suggested replacement: <000801c3a54f$1cc29720$befba8c0@semantix.private.gr>

(suggesting CSI ? 62 ; 1 ; 2 ; 6 ; 7 ; 8 ; 9 c). Haven't analysed this

solution yet.



There have been several reports of our inaccurate response causing

trouble with VMS hosts.
