To install and configure a modem, you must connect the modem to a hardware port, add a new record to the modem table and, in some situations, configure a modem bank (Mbank) record for that modem.
During the installation and configuration, the system does the following if it detects modem errors:
-
Generates an alarm
-
Marks the connection as offscan
-
Marks the modem as out-of-service
Omnicomm and Monitor Mbank control modems by maintaining a current modem state. The current state of the modem is controlled through Administrator-initiated requests and modem-initiated signals.
A modem can be in one of eight possible states, as shown in the following table.
|

|

|

One of the following is true:
|
|
Disabled |
The modem has been manually disabled through a Controller request and made unavailable for use. |
|
In Progress |
The host is attempting to dial the connection through the modem. |
|
Connected |
The host is connected and is executing any commands requested through the modem. |
|
