Networking APIs
The API provided by Intermec Technologies exposes a limited set of rou-
tines
that allows a programmer to access and affect the 802.1x network
interface card from within their application. The routines provided also
reads/writes values to the CE registry that pertain to the 802.1x radio
driver.
By using the provided functions, a programmer can alter the 802.1x
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 present
in any load with the 802.1x networking installed.
PRISMNDS.DLL This file is the 802.1x driver. It is present in all 700 CE
loads that use the 802.1x network
interface card.
80211API.DLL This file is an Intermec authored file that provides the pro-
grammer with a set of API calls
to configure or monitor status of the 802.1x network.
80211PM.DLL This handles profile management for radio configurable
values.
URODDSVC.EXE This handles radio configuration and security authen-
tication based on a selected profile.
There is a user interface to this service that provides status of the supplicant
as well as
status of the 8021x authentication process.
ZNICZIO.DLL A replacement for NDISUIO.DLL that supports the
Funk Supplicant.
The Profile Manager supports up to four radio configuration profiles.
These profiles are the same as those set by theWirelessNetwork control
