Since these characters could be sent to the modem using the same two data pins that the port would need hayes smartmodem 2400, they could be sure that such a system would work on every computer. When this was received from the computer, the modem would switch from data to command mode.

In order to filter out these "accidental" sequences, Heatherington's design only hayes smartmodem 2400 to command mode if the sequence was led and followed by a one-second pause, the guard timein which no other data were sent.
