When you say that you can connect to the modem using minicom, does that
mean that you can issue AT commands through minicom and connect the
modem to the Internet?

You can try specifying a log file in the /etc/ppp/peer/provider file and
then read the file after trying "pon provider" to see what is
happening.  That may give you some clues.  If it says something like
"chat script failed", then you can look into the chat script
(/etc/chat/provider or something like that) to see if you need to change
your connection AT commands.

Also, here is a list of ppp-related drivers that I put into /etc/modules:

bsd_comp

ppp_deflate

ppp_async

crc_ccitt

zlib_deflate

zlib_inflate

ppp_generic

slhc

Thank you for your help. Here's my dmesg log:

Right now I can connect to the modem using minicom. I changed the band to 850 
Mhz (my internet provider's band) and enabled all functionality of the device. 
After that I created a new connection with pppconfig but when I select to find 
the modem automatically, it complains about not finding one.

Then I select /dev/ttyS0 manually, here's my config:

Number   *99#                 Telephone number

   Change DNS
Add-User                          Add a ppp user
Remotename   kolbi3g              Change remotename
Idle-timeout none                 Idle timeout

These parameters were taken from a wvdial config file that I use to connect 
through a Huawei USB 3G module and work fine, so I don't really know what is 
going on...

I'm thinking about going back to kernel 2.4 and check that I'm doing everything 
correctly.

wvdial works with the 2.4 kernel, but there is a bug in the 2.6 kernel
on the arm platform:

m(".../msg279471.html","//www.mail-archive.com/debian-bugs-closed");">http:
http://code.google.com/p/wvstreams/issues/detail?id=26

I was able to get the TS-GSM1 to work with the TS-7260 using the
2.6.21-ts kernel by using pppconfig instead of wvdial.  Then, to connect
I just type "pon provider" and to disconnect type "poff provider", where
'provider' is the name of the provider that you specify in pppconfig.

Hope that helps.

Hello, I'm trying to connect to the internet using the TS-GSM1 module, kernel 
2.6.21-ts and Debian Etch. I have compiled and loaded all the modules and the 
modem is detected correctly, but when I try to use it with wvdial sometimes is 
detected and sometimes not. How did you manage to use it? did you use wvdial or 
pppd? Right now I want to use pppd directly since I have had problems with 
wvdial in the past, if you can give some hints on how to make this module work 
I would be very thankful!

I am running a TS-7260 with lenny user space, a 2.6.21-ts kernel, and a TS-GSM1 
expansion card.  I am streaming data across the cellular modem link using ssh 
port forwarding.  I notice that after a day or so of testing, I will often 
observe unusual behavior with the board that goes away after rebooting.  For 
example,

(1) In one case, after terminating the test, I attempted to ping the remote IP address 
and received this message "ping: sendmsg: No buffer space available".  Odd.
(2) In another case, after the board had been up for a day, I attempted to look 
at some of the pppd configuration files.  Although the files were visible with 
an 'ls', if I attempted to 'more' them, I would be told that the files did not 
exist.
(3) After streaming data for 4 days over the ethernet connection (instead of the 
TS-GSM1), I noticed an error message in the console window: "ERROR: (device 
tssdcarda4): DT_GETPAGE: dtree page corrupt."  When I attempted to move files 
around, I was told that the file system was read only.  After rebooting, things 
functioned normally.
(4) After running for about a day, I attempted to run g++ and it seg faulted.  
I attempted to run apt-get to reinstall g++, and it returned with undefined 
symbol errors.  After rebooting, things functioned normally.

I'm wondering if anyone else has experienced problems like these, and if anyone 
has any ideas of what could be causing them.  I thought that maybe there is a 
memory leak somewhere, but I don't know how I would even check for that.  Any 
assistance is appreciated.
