|
.Sh DESCRIPTION
|
|
The
|
|
.Nm boca
|
|
driver provides support for BOCA Research BB1004, BB1008 and BB2016
|
|
boards that multiplex together up to four, eight or sixteen
|
|

.Tn RS-232C

|
.Tn V.28 )
|
|
communications interfaces.
|
|
.Pp
|
|
Each
|
|
.Nm
|
|
device is the master device for up to eight
|
|
.Nm com
|
|
devices. The kernel configuration specifies these
|
|
.Nm com
|
|
devices as slave devices of the
|
|
.Nm
|
|
device, as shown in the synopsis. The slave ID given for each
|
|
.Nm com
|
|
device determines which bit in the interrupt multiplexing register is
|
|
tested to find interrupts for that device.
|
|
The
|
|
.Tn port
|
|
specification for the
|
|
.Nm
|
|
device is used to compute the base addresses for the
|
|
.Nm com
|
|
subdevices and the port for the interrupt multiplexing register.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
driver was written by Charles Hannum, based on the
|
|
.Nm 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.
