If you don't get the same results as above on the Boca ports
then it is broke!
Whats broke is yet to figure out.
Have you read: man 4 sio

Never said the *modem* was broke.
I said *it's* broke, Meaning that something isn't right.

Thats correct, But did you do this AFTER enabling COM_MULTIPORT,
recompiling and rebooting?
ie: After you saw the boot messages saying that sio4-11 are
found??
I'll run down the steps as I see em from what I've read, I have not
actually done it with a Boca board.
Add options COM_MULTIPORT, sio4-11 to kernel config as stated in
man 4 sio.
# config YOURKERNEL
# cd ../../compile/YOURKERNEL
# make
# make install
# halt (shutdown now)
Power down, Install Properly configured Boca Board.
Power up, boot messages should pick up the sio4-11
# cd /dev
# sh MAKEDEV cuaa4 (thru 11)
# sh MAKEDEV ttyd4 (thru 11)
(I would reboot here, Although I belive it's not needed, I'm just
that way)
# cu -l cuaa4
Connected
AT <enter>
(should result: OK)
If not something is broke! and is above what I can do for you.
I personally don't use Boca boards so I know very little about them.

Is this what your sio11 looks like??
>From the man 4 sio page it states:
device sio11 at isa? port 0x338 tty flags 0xb05 irq 12 vector siointr
^^^^^^^^^^^^^^^^^^^^^
That is the MASTER PORT! according to 'flags 0xb05'
Change the IRQ to fit your Boca board of course!
-Enjoy
