Control Codes for Terminal ST - VT52
------------------------------------
ESC A
Cursor Up
This sequence moves the cursor up one line. If the cursor is already on the
top line of the screen, this sequence has no effect.
ESC B
Cursor down
This moves the cursor down one line. If the cursor is already on the last
line of the screen, this escape sequence has no effect.
ESC C
Cursor Forward
This moves the cursor one position to the right. If this function would
move the cursor off the screen, this sequence has no effect.
ESC D
Cursor Backward
This moves the cursor one position to the left. This is a non-destructive
move because the character over which the cursor now rests is not replaced
by a blank. If the cursor is already in column 0, this escape sequence has
no effect.
ESC E
Clear Screen (and Home Cursor)
This moves the cursor to column 0, row 0 (the top left-hand corner of the
screen), and clears all characters from the screen.
ESC H
Home Cursor
This moves the cursor to column 0, row 0. The screen is NOT cleared.
ESC J
Erase to End of Page
Erases all the characters from cursor (including cursor position) to the
end of the page.
ESC K
Clear to End of Line
This sequence clears the line from the current cursor position (including)
to the end of the line.
ESC L
Insert Line
Inserts a new blank line by moving the line that the cursor is on, and all
following lines, down one line. Then, the cursor is moved to the beginning
of the new blank line.
ESC M
Delete Line
Deletes the contents of the line that the cursor is on, places the cursor
at the beginning of the line, moves all the following lines up one line,
and adds a blank line at the bottom.
ESC Y
Position Cursor
The two characters that follow the "Y" specify the row and column to which
the cursor is to be moved. The first character specifies the row, the
second the column. Rows and columns numbers are biased with $20 (hex) and
the left upper corner of the screen is row 0, column 0.
ESC e
Enable Cursor
This sequence causes the cursor to be visible.
ESC f
Disable Cursor
This sequence causes the cursor to be invisible. The cursor may still
be moved about on the display, using the escape sequences defined here.
ESC p
Enter Reverse Video Mode
Enters the reverse video mode so that characters are displayed as background
color characters on a foreground colored cell.
ESC q
Exit Reverse Video Mode
Exits the reverse video mode.
