5 Asynchronous Operating Commands Response Commands, CEonxta.mple: The ATD5551212 command has been executed, and the phone is busy. To repeat the instruction type A/ , but do not use AT before this command as AT would empty the buffer and there would be no command to repeat. Numbered Commands Series of commands that start with the same letter are distinguished by a number following the letter. For example, the M0 command selects speaker always off, M1 speaker on until carrier detected, and M2 selects speaker always on. In all cases, the zero (0) may be omitted so the commands M and M0 are identical. For clarity, this manual uses the nonzero form of commands. The modem treats both the same but zeros count against the buffer total. Group Commands A group of commands can be typed in a single command statement. Pressing the return key sends the entire command string to the modem, which executes each command individually in the order it appears in the command statement reading from left to right. For example, the command statement ATQ0V0L3DT5551212 means ¥AT Attention. ¥Q Allow response messages to be sent. ¥V Select digit code responses. ¥L3 Select high volume. ¥DT Tone dial 555-1212.
