-A \fBreset\fP command appeared in 2BSD (1979), written by Kurt Shoens.
+A \fBreset\fP command appeared in 2BSD (April 1979), written by Kurt Shoens.
+This program set the \fIerase\fP and \fIkill\fP characters
+to \fB^H\fP (backspace) and \fB@\fP respectively.
+Mark Horton improved that in 3BSD (October 1979), adding
+\fIintr\fP, \fIquit\fP, \fIstart\fP/\fIstop\fP and \fIeof\fP characters
+as well as changing the program to avoid modifying any user settings.
+.PP
+Later in 4.1BSD (December 1980),
+Mark Horton added a call to the \fBtset\fP program
+using the \fB\-I\fP and \fB\-Q\fP options, i.e.,
+using that to improve the terminal modes.
+With those options,
+that version of \fBreset\fP did not use the termcap database.

 A separate \fBtset\fP command was provided in 2BSD by Eric Allman.

+In September 1980, Eric Allman modified \fBtset\fP,
+adding the code from the existing \*(lqreset\*(rq
+feature when \fBtset\fP was invoked as \fBreset\fP.
+Rather than simply copying the existing program,
+in this merged version, \fBtset\fP used the termcap database
+to do additional (re)initialization of the terminal.

 This version appeared in 4.1cBSD, late in 1982.
