+ A <STRONG>reset</STRONG> command appeared in 1BSD (March 1978), written by Kurt Shoens.
This program set the <EM>erase</EM> and <EM>kill</EM> characters to <STRONG>^H</STRONG> (backspace) and <STRONG>@</STRONG>
respectively. Mark Horton improved that in 3BSD (October 1979), adding
<EM>intr</EM>, <EM>quit</EM>, <EM>start</EM>/<EM>stop</EM> and <EM>eof</EM> characters as well as changing the
- program to avoid modifying any user settings.

- Later in 4.1BSD (December 1980), Mark Horton added a call to the <STRONG>tset</STRONG>
- program using the <STRONG>-I</STRONG> and <STRONG>-Q</STRONG> options, i.e., using that to improve the
- terminal modes. With those options, that version of <STRONG>reset</STRONG> did not use
- the termcap database.

- A separate <STRONG>tset</STRONG> command was provided in 2BSD by Eric Allman. While the
- oldest published source (from 1979) provides both <STRONG>tset</STRONG> and <STRONG>reset</STRONG>,
- 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 <STRONG>tset</STRONG>, adding the code from the
- existing "reset" feature when <STRONG>tset</STRONG> was invoked as <STRONG>reset</STRONG>. Rather than
- simply copying the existing program, in this merged version, <STRONG>tset</STRONG> used
- the termcap database to do additional (re)initialization of the
- terminal. This version appeared in 4.1cBSD, late in 1982.
+ According to comments in the source code, the <STRONG>tset</STRONG> program was modified

Other developers (e.g., Keith Bostic and Jim Bloom) continued to modify
<STRONG>tset</STRONG> until 4.4BSD was released in 1993.
