Hello,
I am having some problems getting the modem on my 3Com
mutifunction card to work. The model number of the
card is 3CCFEM556B. I can get ethernet to work with
pccard and the ep driver but am unable to get the
modem working with the sio driver. I am running
FreeBSD 5.0 - Current (20010220).
I gathered the following information about the card
from Windows:
Ethernet
I/O Range 02F8 - 02FF
I/O Range 0120 - 012F
Interrupt 10
Memory Range 08000000 - 08001FFF
Modem
Port - COM2
Interrupt 10
UART NS16550AN
Address 2F8
Both the ethernet and modem seem to share interrupt
10. Is there a kernel option or flag I need to enable
for
interrupt sharing? Currently, I switch from ethernet
to modem by changing the pccard.conf and rebooting. My
pccard.conf for this particular card (for the modem)
is shown below:
io 0x240-0x360
irq 3 5 10 11 15
memory 0xd4000 96k
# 3COM Megahertz 3CCFEM556B
card "3Com" "/Megahertz 3C(CF|X)EM556/"
#config default "ep" ? 0x1
config default "sio" ?
insert /etc/pccard_ether $device start
remove /etc/pccard_ether $device stop
With the above configuration I get the following
dmesg:

I apologize for the huge output but maybe you'll be
able to catch something I couldn't. It recogizes COM1
(physical serial port in the back of the laptop) and
it even finds the modem on sio1 (COM2) on irq 3 but
when I try to use the terminal with the userland PPP
package....the system hangs. Also it recognizes the
card as type 8250 when we know it is 16550A (from
Windows configuration). I tried it with both polling
and non-polling, setting the pcic irq to 10 but it
hung both times.
Any suggestions?
Thanks in advance for any help
Cheers,
Swamy
