3Com Bluetooth PC Card driver
bt3c* at pcmcia? function ?
The bt3c driver provides support for the 3Com Bluetooth
  PC Card, model 3CRWB6096, to the Bluetooth protocol stack.
This card needs firmware loaded before it will work. Due to copyright
  restrictions we cannot distribute the firmware with NetBSD, but if you have
  the card then you should have received a CD with the drivers on, or you may
  download the latest version from the 3Com website. Create a directory named
  bt3c in the search path of the
  firmload(9) kernel subsystem.
  Now, extract the driver archive and find the firmware file called
  BT3CPCC.bin, and place this file in the newly created
  directory. The firmware will be loaded automatically as needed.
  - bt3c%d: Cannot open firmware
- This will be printed to the console if the device cannot open the firmware
      file as described above.
    
  
- bt3c%d: Antenna In
-  
- bt3c%d: Antenna Out
- If the kernel is compiled with the DIAGNOSTICoption, these messages will be produced on the console when the card
      antenna position is changed.
- bt3c%d: sleeping
-  
- bt3c%d: waking up
- These messages will be produced when the card is enabled or disabled due
      to power change events.
Thisbt3c device driver was written by
  Iain Hibbert using FreeBSD and
  BlueZ drivers as a reference. It first appeared in NetBSD
  4.0.
