Hi, Debian!
I've installed Debian 3.0 (Woody) on a new(ish) PC from the set of 8
CD-Roms released in summer 2002. I'm having some trouble configuring my
PCI serial modem. Would somebody here point me towards a solution,
please?
*************************************************************************
I've installed the following "big friendly" kernel (output from uname
-rsv):
Linux 2.4.18-bf2.4 #1 Son Apr 14 09:53:28 CEST 2002
*************************************************************************
My modem, an internal serial PCI modem, is at port 0xb000 irq 4. I know
this by looking at /proc/pci. The relevant entry in this "file" is:
Bus 0, device 11, function 0:
Communication controller: Lucent Microelectronics Venus Modem (V90, 56KFlex) (rev
0).
IRQ 4.
Master Capable. No bursts. Min Gnt=252.Max Lat=14.
Non-prefetchable 32 bit memory at 0xde000000 [0xde0000ff].
I/O at 0xb000 [0xb0ff].
I/O at 0xb400 [0xb4ff].
I/O at 0xb800 [0xb807].
Through a trial installation of a different OS version (SuSE Linux 7.0),
I know that the modem itself is in working order.
*************************************************************************
I want to use the modem on /dev/ttyS2. I therefore type the following
command (as root, of course), all in accordance with the modem's fine
manual:
# setserial /dev/ttyS2 uart 16550A port 0xb000 irq 4
This returns the error message:
"Cannot set serial info: Address already in use"
which I don't understand. Presumably "Address" means "port address
0xb000", but I haven't a clue what "already in use" could mean. What is
this error message telling me? What do I have to do (if anything) to
take it "out of use" first?
*************************************************************************
On booting up, the following relevant seeming messages were written to
/var/log/messages:
Nov 5 20:39:45 acm kernel: Serial driver version 5.05c (2001-07-08) with MANY_PORTS
SHARE_IRQ SERIAL_PCI enabled
Nov 5 20:39:45 acm kernel: PCI: Found IRQ 4 for device 00:0b.0
Nov 5 20:39:45 acm kernel: PCI: Sharing IRQ 4 with 00:07.2
Nov 5 20:39:45 acm kernel: PCI: Sharing IRQ 4 with 00:07.3
Nov 5 20:39:45 acm kernel: ttyS04 at port 0xb000 (irq = 4) is a 16550A
What does this last line mean? What is "ttyS04"? (I haven't got a
/dev/ttyS04 at all, I don't even have a /dev/ttyS4.) Is this line an
indication of port 0xb000 coming into "use"?
*************************************************************************
Any pointers to getting my modem going would be appreciated in the
extreme. Thanks in advance!
