The motivation for this page was curiosity and interest in historical correlations.
Find out stty defaults with
stty(1). Calling it without arguments shows the differences from the defaults.
You might not notice unusual defaults if you are logged in remotely

sshd(8) logs you in differently and even tries to "export" your old settings.
Not to mention shell profiles changing settings, in this concern.
In the following, "^X" means "<Ctrl-X>". See also an article in a.f.c, <62097@bbn.BBN.COM>, about a possible origin of the "^"-notation.
Also see an article from Christian Weisgerber providing some background about the BackSpace vs. Delete issue.
