|
| testing purposes. |

S38 | 0 | Sets the duration, in seconds, before a |
|
| forced |
|
| Transmit buffer, when DTR drops during |
|
| an ARQ call. This is provided to allow |
|
| time for a remote modem to acknowledge |
|
| receipt of all transmitted data. Default = |
|
| 0: the modem immediately hangs up |
|
| when DTR drops. If the modem receives |
|
| the ATH command, it ignores S38 and |
|
| immediately hangs up. |
