It does not hang. It waits for you to switch the baudrate  and  press
ENTER.

This is an ugly hack,and strongly discouraged.

The way the baudrate change is implemented in PPCBoot is  intentional
-  it prevents you to enter a baudrate which you cannot use with your
terminal. If you cannot type the  enter  and  the  "saveenv"  command
necessary to store the new baudrate permanently, you can always reset
the board ans it will come up with the old, working baudrate.
