I am trying to install a 4 port Boca board and configure Linux
to recognize it. Recently on the newsgroup there was some
discussion of multi-port boards (March 17). In the discussion
it was implied that Linux supports the Boca board. However, when
I looked at serial.c I found support for AST FourPort and Accent
Async board but no mention of the Boca board. Is the Boca board directly
compatible with one of these two boards or do I have to modify the
serial.c file? I am sure it's not too hard to modify serial.c to
include the 4 port Boca board. Has someone done this? If so, I would
greatly appreciate any help and information you can give.
Although they're aren't any comments stating this (maybe there should
be), the BocaBoard and the Usenet Serial II board can be used with the
current serial.c as /dev/ttyS16 ... /dev/ttyS19 (or /dev/ttyS23 or
/dev/ttyS31 if you have a BocaBoard 8 or 16, respectively).
Just configure the board to use a base address of 0x100; and turn on
CONFIG_AUTO_IRQ if it works for your system. (It doesn't work on some
systems, for some unknown reason). If AUTO_IRQ doesn't work, then you
should configure your BocaBoard or Usenet Serial II to use IRQ 12, and
if you are running 0.99pl7, you will need to edit serial.c to change IRQ
used by those devices to be IRQ 12. (If you are running 0.99pl7A, this
change has already been made; if you're not sure about modifying
serial.c, just get 0.99pl7A.)
Good Luck!
