The API provided by Intermec Technologies exposes a limited set of rou-
tines that allows a programmer to access and affect the 802.11b network
interface card from within their application. The routines provided also
reads/writes values to the CE registry that pertain to the 802. 11b radio
driver. By using the provided functions, a programmer can alter the
802.11b parameters of Network Name (SSID), WEP keys, infrastructure
modes, radio channel, and power management modes. A programmer can
also retrieve network connect status and signal strength indication from
the RF network card.
The API is contained within the 80211API. DLL file that should be pres-
ent in any load with the 802.11b networking installed.
NETWLAN.DLL
PRISMNDS.DLL
This file is the 802.11b driver. It is present in all 700 CE loads

802PM.DLL This handles profile management for radio configurable values.
URODDSVC.EXE This handles radio configuration and security authentication
based on a selected profile.
The Profile Manager supports up to f our radio configuration profiles.
These profiles are the same as those set by the Wireless Network control
