|
- Execute a chat script directly:
|
2025-03-14 21:59:59 -06:00
|
|
|
|
|
|
|
|
`chat '{{expect_send_pairs}}'`
|
|
|
|
|
|
|
|
|
|
- Execute a chat script from a file:
|
|
|
|
|
|
|
|
|
|
`chat -f '{{path/to/chat_script}}'`
|
|
|
|
|
|
|
|
|
|
- Set a custom timeout (in seconds) for expecting a response:
|
|
|
|
|
|
|
|
|
|
`chat -t {{timeout_in_seconds}} '{{expect_send_pairs}}'`
|
|
|
|
|
|
|
|
|
|
- Enable verbose output to log the conversation to `syslog`:
|
|
|
|
|
|
|
|
|
|
`chat -v '{{expect_send_pairs}}'`
|
|
|
|
|
|
|
|
|
|
- Use a report file to log specific strings received during the conversation:
|
|
|
|
|
|
|
|
|
|
`chat -r {{path/to/report_file}} '{{expect_send_pairs}}'`
|
|
|
|
|
|
|
|
|
|
- Dial a phone number using a variable, substituting `\T` in the script:
|
|
|
|
|
|
|
|
|
|
`chat -T '{{phone_number}}' '{{"ATDT\\T CONNECT"}}'`
|
|
|
|
|
|
|
|
|
|
- Include an abort condition if a specific string is received:
|
|
|
|
|
|
|
|
|
|
`chat 'ABORT "{{error_string}}" {{expect_send_pairs}}'`
|
