iwictl —
configure Intel(R) PRO/Wireless 2200BG/2915ABG network
  adapters
The iwictl utility controls the operation of Intel(R)
  PRO/Wireless 2200BG/2915ABG networking devices via the
  iwi(4) driver.
You should not use this program to configure IEEE 802.11
    parameters. Use ifconfig(8)
    instead.
The options are as follows:
  - -iiface
- Displays adapter's internal statistics.
- -iiface- -r
- Displays the radio transmitter state (on or off).
The firmware is shipped with NetBSD. See
  iwi(4) for details how to use it.
