Global Commands
The AT commands in the following sections are global, meaning that they can be issued in any appropriate mode (i.e., any #CLS setting). For consistency, the command set is divided into action commands and parameters (non-action commands). Those commands, which are action commands (i.e., those that cause some change in the current operating behavior of the modem) are identified as such, and the remaining commands are parameters.
1.1
ATA - Answering in Voice
The answer action command works analogously to the way it works in Data and Fax Modes except for the following: 1. When configured for Voice Mode (#CLS=8), the modem enters Online Voice Command Mode immediately after going off-hook. When the#CLS=8 command is issued, the modem can be programmed to look for 1100 and 1300 Hz calling tones (see #VTD), thus eliminating the need to do so as part of A command processing. After the VCON message is issued, the modem re-enters Online Voice Command Mode while sending any incoming DTMF or Calling Tone indications to the DTE. After answering in Voice Mode (#CLS=8), the DTE, as part of its call discrimination processing, can decide to change the #CLS setting to attempt receiving a fax in Class 1, or to make a data connection. In such a case, the DTE commands the modem to proceed with the data or fax handshake via the A command even though the modem is already off-hook.
1.1.1
Parameters: Same as Data and Fax modes.
1.1.2
Result Codes: VCON Issued in Voice Mode (#CLS=8) immediately after going off-hook.
