Kevin / Steve / RED :

Thanks for the suggestions. After checking all of your suggestions 
without success I convinced myself that I must have missed something in 
checking the config files for correct variable values.  The config files 
were correct ... except for "duplex" ... which was set for half instead 
of full duplex.  Sigh.  (I sure hope confession really is good for the 
soul.)
