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 will
also read/write 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 that has the 802.11b networking installed.
S NETWLAN.DLL
This file is the 802.11b driver. It will be present in all 700 CE loads that
use the 802.11b network interface card.
S 80211API.DLL
This file is an Intermec authored file that provides the programmer with
a set of API calls to configure or monitor status of the 802.11b network.
S MOD80211.DLL
The CORE module for the 802.11b NIC. It provides the 802.11b sta-
tus information displayed when the CORE application is running.
S 80211CONF.EXE
This is the “Control Panel” for configuring the 802.11b network para-
meters. Note that it is an EXE file and is actually called by
CPL802.CPL (see below). It is also called by the CORE application
when the “Configuration” button is pressed.
S CPL802.CPL
A control panel application that does nothing but call
80211CONF.EXE.
S 80211SCAN.EXE
Internally manages the Scan List activity.
The 80211API.DLL supports an unlimited number of radio configuration
profiles. These profiles a re the same as those set by the Wireless Network
control panel applet that runs on the Windows CE unit. You can configure
different 802.11b profiles and switch between them using the 802.11 API.
See the ConfigureProfile() function on page 106 for more information.
