Having problems getting a Boca BB-1008 multiport serial board to work with Linux. I have the board setup at IRQ 12 and IO starting at 0x100. Linux boots and does its autodetection (as configured in r rc.serial) and it see's the ports at the appropriate IO addresses and the correct IRQ. But, when I try echoing something to /dev/cua16 or any of the other configured ports I get nothing on the line. Is there something I need to do to the kernel in order fo ir to work with this board?

If you are using the cables that came with the card, they are most
likely terminal cables, not modem cables. Try a null modem adapter to
check for this. The BB1008 cards do not work well with modems due to
missing modem control signals.

If your using a later kernel than 1.0.8 then you will have to probally do
the same hack I had too for the BB2016 card. Used to be you could add a
statement in the config.in file to do this. But this no longer works with
the new serial code. Instead you need to edit the /usr/src/linux/drivers/char/
serial.c file, in here search for #define BOCA_FLAGS 0 and change this to
#define BOCA_FLAGS ASYNC_BOOT_AUTOCONFIG
Now recompile and enjoy. Worls great on my slip server with 16 USR modems
connected to it.

you do not need to hack the kernel to get serial boards working just use
setserial it will let you configure all your ports exactly as you want
