If the dial string is omitted, and the semicolon included, the command instructs the ME to do a network detect. If the network is available OK is returned.
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.
