It seems you configured miniom to send a modem init string.  This  is
not expected by PPCBoot.

You use minicom.

You post to the wrong list (u-boot-users is a much better  place  for
such questions).

You don't provide any details. Maybe the serial driver on your  board
is waiting for a hardware handshake signal (DCD?) which is down while
disconnected? What happens when you disconnect the cable?

I see that Microsoft's campaign  to  destroy  all  knowledge  of  any
operating   environment   but  its  own  environment-of-the-year  has
succeeded in creating a generation of users who don't understand  the
concept of a shell...
