Notes:

1. Numeric mode: Result code <CR>.

2. Response for ATDn@mmm is silence is not found.

3. This message is supported only on the Si2493, Si2457, Si2434, and Si2415.

4. This message is supported only on the Si2493, Si2457, and Si2434.

5. X is not preceded by <CR><LF>.

6. This message is supported only on the Si2493 and Si2457.

7. V.44 with data compression disabled (+DS = 0) emits this result code.

8. If data compression is disabled (+DS = Q), the modem returns the message PROTOCOL:V42.
