Networking APIs
The API provided by Intermec Technologies exposes a limited set of 
routines that allows a programmer to access and affect the 802.11b/g 
network interface card from within their application. The routines 
provided also reads/writes values to the CE registry that pertain to the 
802.11b/g radio driver. By using the provided functions, a programmer can 
alter the 802.11b/g 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 802.11b/g networking installed.
The Profile Manager supports up to four radio configuration profiles. 
These profiles are 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/g profiles and switch between them using the 802.11 
API. See 
Basic Connect/Disconnect Functions
Below are functions available for the 751G when enabled with the 
802.11b/g radio module.
RadioConnect()
Connects to the available radio. Use this function if you plan on using a lot 
of API calls that talk directly to the radio. Note that the 802.11b/g radio 
must be enabled via NDISTRAY before you can connect to it.
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/g network.
80211PM.DLL
This handles profile management for radio configurable values.
URODDSVC.EXE This handles radio configuration and security authentication 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 80211b/g 
authentication process.
ZNICZIO.DLL
A replacement for NDISUIO.DLL that supports the Funk Supplicant.
Syntax
UINT RadioConnect( );
Parameters
None.
Return Values ERROR_SUCCESS when successful, otherwise 
ERR_CONNECT_FAILED
Remarks
Call this function before you call any other function found within this 
API. It hunts out and connects to the 802.11b/g radio available on the 
system. Check extended error codes if it returns anything for information.
