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