how to go landscape mode with android emulator

http://discuz-android.blogspot.com/2008/01/change-android-screen-landscapeportrait.html

On the emulator, after the Android system is started up, open another command window, type the following command line in the adb shell to change the screen to landscape:
# service call window 18 i32 1
type the following command line to change the screen to portrait:
# service call window 18 i32 0

the above didn't work but using the keypad's 7 key works (so does 9)
