Connection Messages
Once you connect to the remote Modem, your Modem will respond with
one of the following messages. (If the remote Modem responds with
garbled characters or seems to have locked up, refer to
Setting Up For a
Non-Error Correcting Connection
before you try again.)
The Modem may respond with a short form (numeric code) or a long form
(prompt). Refer to the ATXn command description in Section Three to
control how the Modem responds.
