I think the confusion here is comparing the Teletype machines and the IBM

That's my recollection also. The model 28s used a "mode shift" key or
some such to effectively double the character set. If the "mode
shift" code arrived garbled, the receiving machine would miss
everything that followed and print gibberish.


For such a mechanical contraption, they were amazing.
