Laptop GTW V.92 Voicemodem / No Dial-tone
 

Hello:

I have been lent the assistance of someone in the Laptop forum over the past few days to set up a modem driver for my Laptop's 'winmodem', internal GTW V.92 Voicemodem. This is a PCI device.

For your reference, the thread for that is:

http://www.linuxquestions.org/questi...291#post759291

(See the thread for the details of the scanmodem script I ran which confirmed the chipset as Intel AMR and is repleat with diagnostic information about my Laptop's hardware).

My laptop has two partitions, the first is WinXP, the second is RedHat Fedoro and I use GRUB to select which O/S I want.

When in the control panel for WinXP, my modem configuration shows it is using device COM3

Basically, to make a long story short, the person helping me narrowed down and troubleshooted the problem very nicely. We got to the point where a specific modem driver was selected from the SmartLink website:

http://www.smlink.com/main/item.php?...=84&main_id=32

I tussled with it for a while until I figured out that I needed to set the Makefile's KERNEL_INCLUDES to point into the correct /usr/src directory.

At that point I could link and compile and then ran the "make install-amr" per the README file instructions.

Then running kppp, I could interrogate the modem with the "Query Modem" and have it return a series of ATI responses.

Yet, when I tried to dial with kppp, it gets as far as attempting to dial (ATDTmy isp phone#) with "OK" responses and then says in the panel "Expecting CONNECT" and I don't hear any dial-tone.

The default for the Makefile showed it was to set and link /dev/modem to ./ttySL0.

I ran "make uninstall", changed the Makefile and tried to #define MODEM_DEV to either ./ttySL2 and ./ttyS2, verified that query modem responded and then ran kppp still with no dial tone.

Any ideas on what I should try next?
Your help would be most appreciated.

Thanks!

Follow up information
 

I failed to mention the laptop is a Gateway 450SX with 512mb of memory.

P.S. Special Thanks go to morphinjunky for getting me this far along!

One more tidbit
 

Here is a url of a user who has a similar (if not the same) Laptop modem as mine:

http://members.cox.net/arickiver1/gw450x.html

Based on that configuration, a SmarkLink driver was indeed selected and he/she was able to use it with the Gateway450 Laptop.

So I am hopeful that I can set up mine in similar fashion.

Thanks in advance for any assistance you can offer!

Additional Info
 

In looking further at the Winxp hardware configuration, I noticed that the modem device is using IRQ 10 with an address range of:

2000-20FF and
1C00-1C7F

According to this url "how-to" on serial ports:

http://www.sgmltools.org/HOWTO/Serial-HOWTO/t1607.html

the default IRQ mapping for a device ttyS2 (COM3) is: IRQ 5.

So, based on the instructions in the "Serial-HOWTO" it suggests remapping using "/sbin/setserial" and then setting the correct port address.

The how-to furthers to say one can check the interrupts in /proc/interrupts and the ioport mappings in /proc/ioports

Can anyone respond on this and tell me if I am headed in the right direction?

Thanks!

I'm using a gateway laptop 1450 with the same modem, and for it to work I downloadedthis driver.
