PuTTY wish ansisys-compat

This is a mirror. Follow this link to find the primary PuTTY web site.

summary: Better compatibility with DOS's ANSI.SYS
class: wish: This is a request for an enhancement.
difficulty: fun: Just needs tuits, and not many of them.
priority: dormant: This is an old feature request that we no longer think is relevant.

I've had a report that MS-DOS's old ANSI.SYS behaves differently from PuTTY in two important respects: firstly, ESC[2J homes the cursor as well as clearing the screen, and secondly, auto-wrap wraps immediately when a character is displayed in the rightmost column, whereas PuTTY delays the wrapping until the next character is printed. More importantly, apparently old ANSI.SYS-using applications depend on both of these behaviours.

Neither of these should be PuTTY's default - they would break plenty of more modern applications - but setting them as configurable options would be nice.

SGT, 2024-11-17: classifying this wish as dormant. These days, surely anyone wanting ANSI.SYS compatibility is running the actual ANSI.SYS in Dosbox!
