To enable Esc-sequences:

For Windows NT, Windows 2000 and Windows XP:
Create or edit the CONFIG.NT file. (Usually found in the WINNT\SYSTEM32
directory.)

Add the following line to the file:
DEVICE=%systemroot%\system32\ANSI.SYS

Save CONFIG.NT with the new line.

Check that a copy of ANSI.SYS exists in the specified path location.
Restart the computer to complete the change.

No can do. Apparently java uses the console in a way that ansi.sys gets
ignored.

Thanks
I am using console class of java 1.6. In my system has a file ansi.sys
at winnt/system32.
I just write command "DEVICE=%systemroot%\system32\ANSI.SYS" in
config.nt file but its not working > you have any suggestion.
?

See http://en.wikipedia.org/wiki/ANSI_escape_code#Windows_and_DOS
which I think explains this reasonably well:

"ANSI output from 16-bit legacy programs executing under the NTVDM will
be interpreted"

I guess the JVM isn't 16-bit - though perhaps MS would be happy to label
it legacy

I think this leaves the following choices:

* Use JNI to use the Windows Console API.
* Output sufficient newlines.
* Write a thin Swing wrapper using e.g. a JTextArea.
* etc
