Command <strong>Description</strong><br />

This command requests the ME to transmit a Phase C page. When<br />

the ME is ready to accept Phase C data, it issues the negotiation<br />

responses and the CONNECT result code to the application.<br />

In Phase B, the <strong>AT</strong>+FDT command releases the ME to proceed with<br />

negotiation, and releases the DCS message to the remote station. In<br />

Phase C, the <strong>AT</strong>+FDT command resumes transmission after the end of<br />

a data stream transmited before.<br />
