     com16 at boca? slave ?
     com17 at boca? slave ?

     (The BB2016 is functionally equivalent to two BB1008 boards, and is configured as such.)

DESCRIPTION

     The boca driver provides support for BOCA Research BB1004, BB1008 and BB2016 boards that multiplex together up to four, eight or sixteen EIA
     RS-232C (CCITT V.28) communications interfaces.

     Each boca device is the master device for up to eight com devices.  The kernel configuration specifies these com devices as slave devices of
     the boca device, as shown in the synopsis.  The slave ID given for each com device determines which bit in the interrupt multiplexing regis-
     ter is tested to find interrupts for that device.	The port specification for the boca device is used to compute the base addresses for the
     com subdevices and the port for the interrupt multiplexing register.

FILES

     /dev/tty??

SEE ALSO

     com(4)

HISTORY

     The boca driver was written by Charles Hannum, based on the ast driver and source code from David Muir Sharnoff.  David wishes to acknowledge
     the assistance of Jason Venner in determining how to use the BOCA boards.
