-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.
-While the oldest published source (from 1979) provides both programs,
+While the oldest published source (from 1979)
+provides both \fBtset\fP and \fBreset\fP,
 Allman's comments in the 2BSD source code indicate
 that he began work in October 1977,
 continuing development over the next few years.

-In September 1980, Eric Allman modified \fBtset\fP to provide a \*(lqreset\*(rq
-feature when the program was invoked as \fBreset\fP.
+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.
 .PP
+Other developers (e.g., Keith Bostic and Jim Bloom)
+continued to modify \fBtset\fP until 4.4BSD was released in 1993.
+.PP
 The \fBncurses\fR implementation
 was lightly adapted from the 4.4BSD sources for a terminfo environment by Eric
 S. Raymond <esr@snark.thyrsus.com>.
