To my understanding the way the clear reacts depends on the application you are using. Some Telnet clients clear the screen while some scrolls the things up.

curs_clear
curs_clear(3) Library Functions Manual curs_clear(3)
NAME
curs_clear, clear, wclear, erase, werase, clrtobot, wclrtobot, clrtoeol, wclrtoeol - Clear all or part of a Curses window
SYNOPSIS
#include <curses.h>
int clear(
void ); int wclear(
WINDOW *win ); int erase(
void ); int werase(
WINDOW *win ); int clrtobot(
void ); int wclrtobot(
WINDOW *win ); int clrtoeol(
void ); int wclrtoeol(
WINDOW *win );
LIBRARY
Curses Library (libcurses)
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
clear, wclear, erase, werase, clrtobot, wclrtobot, clrtoeol, wclrtoeol: XCURSES4.2
Refer to the standards(5) reference page for more information about industry standards and associated tags.
DESCRIPTION
The erase and werase routines copy blanks to every position in the window.
The clear and wclear routines are similar to erase and werase but also call clearok. The result is that the screen is cleared completely on
the next call to wrefresh for that window and repainted from scratch.
The clrtobot and wclrtobot routines erase all lines below the cursor in the window. In addition, these routines erase the current line to
the right of the cursor, including the character on which the cursor is positioned.
The clrtoeol and wclrtoeol routines erase the current line to the right of the cursor, including the character on which the cursor is posi-
tioned.
NOTES
The header file <curses.h> automatically includes the header file <stdio.h>.
Note that erase, werase, clear, wclear, clrtobot, and clrtoeol may be macros.
RETURN VALUES
Upon successful completion, these routines return OK; otherwise, they return ERR.
