 .SH DESCRIPTION
-\&\fBTset\fR initializes terminals.
-\fBTset\fR first determines the type of terminal that you are using.
+.SS "\fItset\fP \(em initialization"
+This program initializes terminals.
+.PP
+First, \fB@TSET@\fP retrieves the current terminal mode settings
+for your terminal.
+It does this by successively testing
+.bP
+the standard error,
+.bP
+standard output,
+.bP
+standard input and
+.bP
+ultimately \*(``/dev/tty\*(''
+.PP
+to obtain terminal settings.
+Having retrieved these settings, \fB@TSET@\fP remembers which
+file descriptor to use when updating settings.
+.PP
+Next, \fB@TSET@\fP determines the type of terminal that you are using.
 This determination is done as follows, using the first terminal type found.
 .PP
-1. The \fBterminal\fR argument specified on the command line.
+1. The \fBterminal\fP argument specified on the command line.
 .PP
-2. The value of the \fBTERM\fR environmental variable.
+2. The value of the \fITERM\fP environment variable.
 .PP
 3. (BSD systems only.) The terminal type associated with the standard
-error output device in the \fI/etc/ttys\fR file.
-(On System\-V-like UNIXes and systems using that convention,
-\fIgetty\fR does this job by setting
-\fBTERM\fR according to the type passed to it by \fI/etc/inittab\fR.)
+error output device in the \fI/etc/ttys\fP file.
+(On System\ V hosts and systems using that convention,
+\fI\%getty\fP(8) does this job by setting
+\fITERM\fP according to the type passed to it by \fI\%/etc/inittab\fP.)
 .PP
-4. The default terminal type, \*(``unknown\*(''.
+4. The default terminal type, \*(``unknown\*('',
+is not suitable for curses applications.
 .PP
-If the terminal type was not specified on the command-line, the \fB\-m\fR
-option mappings are then applied (see the section
-.B TERMINAL TYPE MAPPING
-for more information).
+If the terminal type was not specified on the command-line, the \fB\-m\fP
+option mappings are then applied;
+see subsection \*(``Terminal Type Mapping\*(''.
 Then, if the terminal type begins with a question mark (\*(``?\*(''), the
-user is prompted for confirmation of the terminal type.  An empty
+user is prompted for confirmation of the terminal type.
+An empty
 response confirms the type, or, another type can be entered to specify
-a new type.  Once the terminal type has been determined, the terminfo
-entry for the terminal is retrieved.  If no terminfo entry is found
+a new type.
+Once the terminal type has been determined,
+the terminal description for the terminal is retrieved.
+If no terminal description is found
 for the type, the user is prompted for another terminal type.
 .PP
-Once the terminfo entry is retrieved, the window size, backspace, interrupt
-and line kill characters (among many other things) are set and the terminal
-and tab initialization strings are sent to the standard error output.
+Once the terminal description is retrieved,
+.bP
+if the \*(``\fB\-w\fP\*('' option is enabled, \fB@TSET@\fP may update
+the terminal's window size.
+.IP
+If the window size cannot be obtained from the operating system,
+but the terminal description
+(or environment,
+e.g.,
+\fILINES\fP and \fI\%COLUMNS\fP variables specify this),
+use this to set the operating system's notion of the window size.
+.bP
+if the \*(``\fB\-c\fP\*('' option is enabled,
+the backspace, interrupt and line kill characters
+(among many other things) are set
+.bP
+unless the \*(``\fB\-I\fP\*('' option is enabled,
+the terminal
+and tab \fIinitialization\fP strings are sent to the standard error output,
+and \fB@TSET@\fP waits one second (in case a hardware reset was issued).
+.bP
 Finally, if the erase, interrupt and line kill characters have changed,
 or are not set to their default values, their values are displayed to the
 standard error output.
-Use the \fB\-c\fP or \fB\-w\fP option to select only the window sizing
-versus the other initialization.
-If neither option is given, both are assumed.
+.SS "\fIreset\fP \(em reinitialization"
+When invoked as \fB@RESET@\fP, \fB@TSET@\fP sets the terminal
+modes to \*(``sane\*('' values:
+.bP
+sets cooked and echo modes,
+.bP
+turns off cbreak and raw modes,
+.bP
+turns on newline translation and
+.bP
+resets any unset special characters to their default values
 .PP
-When invoked as \fBreset\fR, \fB@TSET@\fR sets cooked and echo modes,
-turns off cbreak and raw modes, turns on newline translation and
-resets any unset special characters to their default values before
-doing the terminal initialization described above.  This is useful
-after a program dies leaving a terminal in an abnormal state.  Note,
+before
+doing the terminal initialization described above.
+Also, rather than using the terminal \fIinitialization\fP strings,
+it uses the terminal \fIreset\fP strings.
+.PP
+The \fB@RESET@\fP command is useful
+after a program dies leaving a terminal in an abnormal state:
+.bP
 you may have to type
 .sp
-    \fB<LF>reset<LF>\fR
+    \fI<LF>\fB@RESET@\fI<LF>\fR
 .sp
 (the line-feed character is normally control-J) to get the terminal
 to work, as carriage-return may no longer work in the abnormal state.
+.bP
 Also, the terminal will often not echo the command.

-Resize the window to match the size deduced via \fBsetupterm\fP.

-The arguments for the \fB\-e\fR, \fB\-i\fR, and \fB\-k\fR
-options may either be entered as actual characters or by using the `hat'
-notation, i.e., control-h may be specified as \*(``^H\*('' or \*(``^h\*(''.

+\fI\%xterm\fP(1) assists this activity.
+.SH HISTORY
+A \fB\%reset\fP command written by Kurt Shoens appeared in 1BSD
+(March 1978).
+.\" https://minnie.tuhs.org/cgi-bin/utree.pl?file=1BSD/s6/reset.c
+It set the \fIerase\fP and \fIkill\fP characters
+to \fB\*^H\fP (backspace) and \fB@\fP respectively.
+Mark Horton improved this \fB\%reset\fP 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.
+.\" https://minnie.tuhs.org/cgi-bin/utree.pl?file=3BSD/usr/src/cmd/\
+.\"   reset.c
+That version of \fB\%reset\fP did not use \fI\%termcap\fP.
+.PP
+Eric Allman wrote a distinct \fBtset\fP command for 1BSD,
+using a forerunner of \fI\%termcap\fP called \fI\%ttycap\fP.
+.\" https://minnie.tuhs.org/cgi-bin/utree.pl?file=1BSD/s6/tset.c
+.\" https://minnie.tuhs.org/cgi-bin/utree.pl?file=1BSD/man7/ttycap.7
+Allman's comments in the source code indicate
+that he began work in October 1977,
+continuing development over the next few years.
+By late 1979,
+it had migrated to \fI\%termcap\fP and handled the \fI\%TERMCAP\fP
+variable.
+.\" https://minnie.tuhs.org/cgi-bin/utree.pl?file=3BSD/usr/src/cmd/\
+.\"   tset/tset.c
+Later comments indicate that \fBtset\fP was modified in September 1980
+to use logic copied from the 3BSD \*(``reset\*('' program when it was
+invoked as \fB\%reset\fP.
+.\" https://minnie.tuhs.org/cgi-bin/utree.pl?file=2.9BSD/usr/src/ucb/\
+.\"   tset/tset.c
+This version appeared in 4.1cBSD, \" and backported to 2.9BSD
+late in 1982.
+Other developers such as Keith Bostic and Jim Bloom continued to modify
+\fBtset\fP until 4.4BSD was released in 1993.
+.PP
+The \fI\%ncurses\fP implementation was lightly adapted from the 4.4BSD
+sources to use the \fI\%terminfo\fP API by Eric S.\& Raymond
+<esr@snark.thyrsus.com>.
