Sure there is, from the output:

Anyway, you get the picture. Let's go find the the entry for sio2,
which is what we decided to use.
I never remember these, so I go to /sys/i386/isa ,and grep from COM3
(remember that we start at sio0, which DOS starts at COM1, so sio2 ==
COM3).
$ fgrep COM3 *.h
isa.h:#define IO_COM3 0x3E8 /* COM3 i/o address */
Ahh, we want 0x3e8.

OK, so far so good. We know the index. But, as long as we're here,
let's finish up everything for the card.

So, we've got everything we need for the card's pccard.conf entry,
except for the IRQ (which we'll hard-code for now to be one of the
available interrupts for that configuration index. This will go away at
some point in the future, since we can simply 'fake' the card into
thinking it's using a valid interrupt while using any free interrupt
from the system.)
# Germany's famouse MicroLink modem card
card "ELSA'Aachen'Germany" "MicroLink 33.6MC"
config 0x32 "sio2" 10
insert echo "Microlink 33.6 modem inserted"
removed echo "Microlink 33.6 modem removed"
Done!

You tell me. Seriously, can you answer that question on your own now
with the information just posted? If so, send the list an email saying
so, or else *please* ask some more questions!
