Post ltmodem support


Hi Guys,

can you help on this ?

I've a dual boot system and cannot definitely destroy the Win XP partition until my modem work on linux. It's time it works.

I run SUSE 9.2 (Linux desktop 2.6.8-22-default #1 Mon Oct 4 20:36:37 UTC 2004 i686 athlon i386 GNU/Linux) and I just installed the last ltmodem rpm available from Suse FTP site (that is ltmodem-8.31a8-6.2)


My modem is the following :
lspci -vv

0000:00:0c.0 Communication controller: Agere Systems (former Lucent Microelectronics) F-1156IV WinModem (V90, 56KFlex) (rev 01)
Subsystem: Askey Computer Corp.: Unknown device 1029
Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort - <MAbort- >SERR- <PERR-
Latency: 0 (63000ns min, 3500ns max)
Interrupt: pin A routed to IRQ 11
Region 0: Memory at de800000 (32-bit, non-prefetchable) [disabled]
Region 1: I/O ports at b800 [size=8]
Region 2: I/O ports at b400 [size=256]
Capabilities: [f8] Power Management version 2
Flags: PMEClk- DSI+ D1- D2+ AuxCurrent=0mA PME(D0-,D1-,D2+,D3hot +,D3cold+)
Status: D0 PME-Enable- DSel=0 DScale=0 PME-

and lspc -nv
0000:00:0c.0 Class 0780: 11c1:044a (rev 01)
Subsystem: 144f:1029
Flags: bus master, medium devsel, latency 0, IRQ 11
Memory at de800000 (32-bit, non-prefetchable) [disabled]
I/O ports at b800 [size=8]
I/O ports at b400 [size=256]
Capabilities: [f8] Power Management version 2

So it seems to be supported as Device ID is 044a.

SCAN MODEM
Running scanmodem I get:

desktop:/usr/share/doc/packages/ltmodem/utils # ./scanmodem


UPDATE=2004 July 7
./scanmodem: line 435: gcc: command not found

Providing detail for device at PCI_bus 0000:00:0c.0
with vendor-ID:device-ID
----:----
Class 0780: 11c1:044a Communication controller: Agere Systems (former Lucent Microelectronics) F-1156IV WinModem (V90, 56KFlex) (rev 01)
SubSystem 144f:1029 Askey Computer Corp.: Unknown device 1029
Flags: bus master, medium devsel, latency 0, IRQ 11
Memory at de800000 (32-bit, non-prefetchable) [disabled]
I/O ports at b800 [size=8]

The modem has a supported Lucent/Agere DSP (digital signal processing) chipset
with primary PCI_ID: 11c1:044a
DSP=1


Therefore it is supported.

Taking a look at the VAR/LOG/MESSAGES I see that:

Dec 11 19:20:43 desktop kernel: lt_modem: no version for "struct_module" found: kernel tainted.
Dec 11 19:20:43 desktop kernel: lt_modem: unsupported module, tainting kernel.

Dec 11 19:20:43 desktop kernel: ltserial: unsupported module, tainting kernel.

Dec 11 19:20:43 desktop kernel: ttyLT0 at I/O 0xb400 (irq = 255) is a AgereModem
Dec 11 19:20:43 desktop kernel: Loading module Agere/Lucent WinModem Interface driver version 8.31 (2004-03-31)

Strange is the IRQ that shoud be 19 (in Windows)

WVDIALCONFIG and WVDIAL
Scanning your serial ports for a modem.

Port Scan<*1>: Scanning ttyLT0 first, /dev/modem is a link to it.
Port Scan<*1>: LT0
ttyS0<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600 baud
ttyS0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200 baud
ttyS0<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.
Port Scan<*1>: S1 S2 S3 S4 S5 S6 S7
Port Scan<*1>: S8 S9 S10 S11 S12 S13 S14 S15

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?


and of course running wvdial I get

desktop:~ # wvdial
--> WvDial: Internet dialer version 1.54.0
--> Cannot open /dev/modem: Input/output error

The same is on /dev/ttyS1 or whatever.

SETSERIAL
desktop:~ # setserial -gva /dev/modem
/dev/modem, Line 0, UART: 16550A, Port: 0xb400, IRQ: 255
Baud_base: 115200, close_delay: 500, divisor: 0
closing_wait: 30000
Flags: spd_normal

The strange thing I see is that running windows the modem is recognized on port COM3 and IRQ19, while linux see ttyLT0 and IRQ 11.
By the way in XP it use the extra initalization command ATM0.


Really I don't want to build module and other stuff is there is something stupid I'm not seeing....

Thanks
