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 fr om within their application. The routines provided also
reads/writes v alues to the C E 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.
