Port 2’s speed must be set properly for the modem. To determine the appropriate port speed, examine the
following table:
To determine the maximum baud rate supported by the modem, the port speed must be set and tested.
Modem handling must be disabled on the port; if it is enabled, the SCS will attempt to initialize the modem
when the port is logged out.
Figure 9-17: Configuring Port Speed
The port speed is tested by logging into the port and sending an attention (“at”) command. The modem
should respond with “OK”. If it does not send “OK”, the port speed should be set to a lower baud rate (see
Table 9-2).
Figure 9-18: Testing the Port Speed
After the appropriate port speed is determined, the port must be configured using the generic modem profile.
In addition, modem operation must be enabled.
To determine which profile number is the generic profile (the number will change as new profiles are
added), enter the List Modem command:
