	this problem was described in the MacLayers Bulletin #1 as follows:

2.  The layers multiple window protocol does not work on 7-bit lines.  It
    should, but it doesn't.  Since file transfer is macput, it also
    needs 8 bit.  Use 8 bit, no parity.  7-bit gets you an "encode request
    not received" message.

	MacLayers Bulletins numbers 1 and 2 were posted both here and in
	INFO-MAC and are archived on RASCAL.ICS.UTEXAS.EDU in

	the bulletin no. 2  contains a bug fix (as follows)

Level: Severe

 Problem 001: The layers command may fail to properly startup protocol mode
              or a new layer window requested by the user may stall.

  Symptoms:   After the user issues the layers command the initial shell
              window appears followed by a "Bad Packet Received" dialog
              box. After that point further input is ignored until the
              layers system is terminated with a Control menu selection
              of "Abort Host Layers".

              A secondary manifestation of this problem can occur after
              layers protocol mode has been established and when a new layer
              window is requested by the user. The window may remain
              inert until it has been put behind another layer window
              and then brought back up to front.
