Here's a test-script which shows the expected behavior.
It shows
        + tab-stops after reset
        + tab-stops after "tabs -4"
        + does a reset
        + shows that the tab-stops are set back to 8.

If SecureCRT doesn't do that, you might want to report it as a bug to
its developer.

I don't see the bug you're talking about with Linux console.

I see that konsole has a bug there, but having seen recent comments
that it doesn't get other stuff right, you might have more trouble
getting it fixed.

If I were to make _any_ change in ncurses to accommodate konsole,
it would be in _its_ terminal descriptions, not for "linux" or
"xterm-256color".

Start with these (extracted from "toe -sa"):

*-*---: konsole         KDE console window
*-*---: konsole+pcfkeys konsole subset of xterm+pcfkeys
*-*---: konsole-16color klone of xterm-16color
*-*---: konsole-256color        KDE console window with xterm 256-colors
*-*---: konsole-base    KDE console window
*-----: konsole-direct  konsole with direct-color indexing
*-*---: konsole-linux   KDE console window with linux keyboard
*-*---: konsole-solaris KDE console window with Solaris keyboard
*-*---: konsole-vt100   KDE console window with vt100 (sic) keyboard
*-*---: konsole-vt420pc KDE console window with vt420 pc keyboard
*-*---: konsole-xf3x    KDE console window with keyboard for XFree86 3.x xterm
*-*---: konsole-xf4x    KDE console window with keyboard for XFree86 4.x xterm
*-*---: screen-bce.konsole      screen optimized for KDE console window
*-*---: screen.konsole  screen in KDE console window
*-----: screen.konsole-256color GNU Screen with konsole using 256 colors

Probably SecureCRT should have a corresponding set, but to date no one's
found it important enough to do this.
