3.1 Logging in
The terminal type indicates to the Unix system how to interact with the session just opened.
Should you need to reset the terminal type, enter the command:
setenv TERM <term type> - if using the C-shell (see Chapter 4.)
(On some systems, e.g. MAGNUS, it's also necessary to type "unsetenv TERMCAP".)
TERM=<term type>; export TERM - if using the Bourne shell (see Chapter 4.)
where <term type> is the terminal type, such as vt100, that you would like set.
