A typographical error or sacrifice when typing the name Bü without umlauts, or when the "ü" character cannot be displayed in the desired situation.

The error message given by a modem when the telephone line carrier signal is lost. In the days of BBSs this was a frequent occurrence, often at the very moment someone was typing a sentence. Loss of signal would cause a string of garbage characters to be displayed to the recipient.

Also the "Free as in Beer" line is...

An exclamation to indicate a spelling or grammatical error.
