In the 8 bit variant you could also interpret it as the Morse Code letter ........, which is an early form of non-printable character known as a "procedure sign" (aka "pro-sign"), and is often transcribed as letters without the inter-letter spacing (Eg <SOS> is the transcription of ...---...). The prosign <eeeeeeee> means the sender has mis-keyed something and you should ignore the previous character.
