One further thought has occured.
Are you possibly using a USB to RS-232 converter on one of the new computers
that come complete without serial ports.
I know of at least two of these devices that do not handle the BREAK
sequence correctly. Since BREAK is common to most Motorola debug start up
sequences, it is not possible to use these converters with such debuggers.
If this is the case, get yourself an old, unloved, legacy machine with
_real_ RS-232 ports and try again.
Good luck, Bob Smith
