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. +That version of \fBreset\fP did not use the termcap database. .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. -.PP -A separate \fBtset\fP command was provided in 2BSD by Eric Allman. -While the oldest published source (from 1979) -provides both \fBtset\fP and \fBreset\fP, -Allman's comments in the 2BSD source code indicate +A separate \fBtset\fP command was provided in 1BSD by Eric Allman, +using the termcap database. +Allman's comments in the source code indicate that he began work in October 1977, continuing development over the next few years. .PP -In September 1980, Eric Allman modified \fBtset\fP, -adding the code from the existing \*(``reset\*('' -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. +According to comments in the source code, +the \fBtset\fP program was modified in September 1980, +to use logic copied from the 3BSD \*(``reset\*('' +when it was invoked as \fBreset\fP.
