GETMSG [portname]

* GETMSG waits for a message arriving at the process-internal
  messageport (pr_MsgPort). The message will be shown, strings
  will be tried to detected (this could cause lots of enforcer hits).
  Then you will be asked if to reply the message. "y" replies it
  and should be used normally. "e" replies and gets back to waiting
  mode again. Abort waiting is possible with CTRL-C.
* "GETMSG portname" gives the process-internal port the given name.
  Then it behaves as described above.
* See  PUTMSG  for examples.
