He then asks how you can send an ANSI ESC sequence to the screen.
Actually, it's kind of hard with the standard commands, but you can
add an ESC.COM utility program which works like ECHO but precedes
the message with an ESC code.  To create the utility program, capture
the text shown below to some file, say ESC.SCR.  Then edit the file
to remove all the lines except those between the equals sign (=) lines.
Then run the command DEBUG, using ESC.SCR as input, with the command:
     c> DEBUG <ESC.SCR
This should produce the file ESC.COM which you can use to send ESC 
sequences.  For example, to change the command shown above, type:
     C>ESC [44m
The script file to create ESC.COM is:
=======================================================================
n esc.com
a
mov bx,0080
add bl,[bx]
mov byte ptr [bx+1],24
mov byte ptr [0081],1b
mov dx,0081
mov ah,09
int 21
int 20
             {Blank line; delete this text.}
rcx
0017
w
q
