| If the telephone and |
|
|
|
| modem share the same |
|
|
|
| line, and DTR is raised, |
|
|
|
| the modem takes control |
|
|
|
| of the phone line and |
|
|
|
| disconnects the voice call. |
|
|
|
| The modem stays on hook |
|
|
|
| for the duration specified |
|
|
|
| in S6 before it becomes a |
|
|
|
| data call. |
|
|
|
| Since there is no way to |
|
|
|
| detect if the telephone is in |
|
|
|
| use, the S6 delay occurs |
|
|
|
| even if the telephone is not |
|
|
|
| in use. |
|
|
|
| The phone is |
|
|
|
| once the modem returns |
|
|
|
| on hook. |
