Figure 334: 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 732).
Configuring the TTY Port
1. View the exposed TTY ports by executing the show usb ports 13 command.
Figure 335: 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 732 for instruction.
2. Send a test AT command to determine the correct modem port.
Figure 336: show usb test command
In the example above, the TTY port responds with an ‘OK’. This indicates that ttyUSB0 is a valid modem port.
There may be more than one modem port; you can continue to send AT commands to determine which ports are
modem ports. If the port is not a valid modem port, a time out error is generated as shown in the example below
Figure 337: Time out error example.
In the example below, the TTY port does not exist, or is busy with a previous PPP session.
