Abortability:
Aborting an ATD command is accomplished by the transmission from the DTE
to the DCE of any character. A single character shall be sufficient to abort the
command in progress; however, characters transmitted during the first 125
milliseconds after transmission of the termination character are ignored. This
is to allow the DTE to append additional control characters such as line feed
after the command line termination character.
