S28 | 8 | Sets the duration, in tenths of a second, of |
|
| the extra 3000/600 Hz answer tones sent |
|
| during V.32 handshaking. This gives V.32 |
|
| modems additional time to connect in V.32 |
|
| mode before timing out. |
If there is difficulty answering older, manually operated V.32 modems, for example, modems that require a button to be pushed in order to dial, try lengthening the duration of the extra tones.
