CHAPTER 4: AT Commands, S-Registers, and Result Codes
Command: | %A | Adaptive Answer Result Code Enable |
Values: |
| n=0 or 1 |
Defaults: |
| 0 |
Description: |
| The %A command controls whether the DATA and |
|
| FAX result codes will be sent by the modem. The |
|
| modem must be in fax mode for this command to |
|
| work. Also, the modem must be set to +FAA=1 |
|
| which enables the modem to distinguish between a |
|
| fax and a data call. When these commands are |
|
| enabled, the modem sends DATA to the computer |
|
| when it detects data tones and FAX when it detects |
|
| fax tones. These strings are used by some servers to |
|
| select the appropriate communication program. |
| %A0 | Disables adaptive answer result codes. |
| %A1 | Enables adaptive answer result codes. |
