Chapter 3: <strong>AT</strong> <strong>Commands</strong> <strong>Reference</strong><br />

When the data transmission is complete, the H24 gets the output wakeup line to high.<br />

Figure 3-3: Wakeup Outline<br />

Two modes exist:<br />

• Idle mode: The H24 has no data to send.<br />

• Wakeup mode: The H24 has data to send to the terminal.<br />

After the H24 changes the line edge to Wakeup mode, there will be a delay (the default is 30 ms)<br />

sent by the ats102 command before sending any data to the terminal (using RS232 protocol).<br />
