Configuring the Profile and Modem Driver
1. Insert the USB Modem into an open USB port.
2. Verify that the modem is detected (the show usb command. (see Figure 233.)
3. If your modem is not recognized (such as type is unknown”, no matching profile, or device not ready”),
use the show usb verbose ( see Figure ) command to verify your modem is listed.
4. From the command-line interface, issue the cellular profile <profile> command to reate a cellular profile and
import the identifiers.The Dialer, TTY, and Driver fields are the new profile defaults
5. Configure the modem driver.
The default “option” driver is a catch-all for cellular modems. Nearly all cards use this driver and support for
new modems are added here. Once option driver is configured to work with this device, it recognizes the
modem and expose its ports.
If you get entries similar to the example below:
Figure 228 Driver=(none)
This means the driver does not work with these ports. Try the other drivers and see if they pick up the
device. Airprime is the reliable catch-all driver, Sierra is for certain Sierra cards, and cdc-acm is a legacy
abstract control modem driver. Your goal is to assign a driver for the unclaimed (none) interfaces (If#).
If no option driver appears or only storage interfaces appear, then the modem must be switched to data
mode (see Switching Modes on page 985).
Configuring the TTY Port
1. View the exposed TTY ports by executing the show usb ports 13 command.
Figure 229 show usb ports 13 command
In the example above, the command reveals four exposed TTY ports. One is the modem port, while the
other ports are for GPS, real-time statistics, or diagnostics. If the command does not reveal any ports or if
only storage devices (such as ‘sr0’) appear, then the device must be switched to data mode before
proceeding. See Switching Modes on page 985 for instruction.
2. Send a test AT command to determine the correct modem port.
Figure 230 show usb test command
In the example above, the TTY port responds with an ‘OK’. This indicates that ttyUSB0 is a valid modem
port.
