|

* This driver also knows how to load the synthesizers in the 2.4 Gz
|
||||
* ISA Half-card, Product number 847647476 (USA/FCC IEEE Channel set).
|
||||
* This product consists of a "mothercard" that contains the 82586,
|
||||
* NVRAM that holds the PSA, and the ISA-buss interface custom ASIC.
|
||||
* The radio transceiver is a "daughtercard" called the WaveMODEM which
|
||||
* connects to the mothercard through two single-inline connectors: a
|
||||
* 20-pin connector provides DC-power and modem signals, and a 3-pin
|
||||
* connector which exports the antenna connection. The code herein
|
||||
* loads the receive and transmit synthesizers and the corresponding
|
||||
* transmitter output power value from an EEPROM controlled through
|
||||
* additional registers via the MMC. The EEPROM address selected
|
||||
* are those whose values are preset by the DOS utility programs
|
||||
* provided with the product, and this provides compatible operation
|
||||
* with the DOS Packet Driver software. A future modification will
|
||||
* add the necessary functionality to this driver and to the wlconfig
|
||||
* utility to completely replace the DOS Configuration Utilities.
|
||||
* The 2.4 Gz WaveMODEM is described in document number 407-024692/E,
|
||||
* and is available through Lucent Technologies OEM supply channels.

|

* This driver also knows how to load the synthesizers in the 2.4 Gz

* ISA Half-card, Product number 847647476 (USA/FCC IEEE Channel set).
|

* This product consists of a "mothercard" that contains the 82586,
|

* NVRAM that holds the PSA, and the ISA-buss interface custom ASIC.
|
||||
* The radio transceiver is a "daughtercard" called the WaveMODEM which
|
||||
* connects to the mothercard through two single-inline connectors: a
|
||||
* 20-pin connector provides DC-power and modem signals, and a 3-pin
|
||||
* connector which exports the antenna connection. The code herein
|
||||
* loads the receive and transmit synthesizers and the corresponding
|
||||
* transmitter output power value from an EEPROM controlled through
|
||||
* additional registers via the MMC. The EEPROM address selected
|
||||
* are those whose values are preset by the DOS utility programs
|
||||
* provided with the product, and this provides compatible operation
|
||||
* with the DOS Packet Driver software. A future modification will
|
||||
* add the necessary functionality to this driver and to the wlconfig
|
||||
* utility to completely replace the DOS Configuration Utilities.
|
||||
* The 2.4 Gz WaveMODEM is described in document number 407-024692/E,
|
||||
* and is available through Lucent Technologies OEM supply channels.
