GPRS modem problems

Mohamed Mydeen A · 12-21-2007, 12:02 AM

Hi,

I am using SuSE Linux 10.1

I want to connect MOXA GPRS/GSM Modem (Model No is: G21501)with my linux system in COM1 port that is ttyS0.

But the OS partly detected the modem and I am not able to communicate properly through my modem.

Expecting your reply...

Thanks

How do you try to communicate with the modem? At the lowest layer easily accessible, connect to the modem with minicom and try some at commands. For instance, AT<enter> should show an echo.

Just do the following:

Code:

[Modem0] 

Modem=/dev/ttyACM0 or ttyS0
Baud=115200 

SetVolume=0 

Dial Command = ATDT 

init1=ATZ 

init2=AT+CGDCONT=1,"ip","<ur APN>" 

FlowControl= Hardware (CRTSCTS) 

[Dialer xyz] 

Username= <ur no> 

Password= <ur no>

Phone=<to dial>

Stupid Mode= 1 

Inherits = Modem0

paste the above in
/etc/wvdial.conf

replace <ur no > with your no.
to dial with the no.u use to connect to gprs for example in bsnl it is *99#
and ur APN with the adress used to connect gprs..check mobile settings.for eg. in bsnl it is gprsnorth.cellone.in

n save it,,

n then cum on the prompt , n type

wvdial xyz

u must be connecting to internet
if this doent happen then on the second line ,, try /dev/ttyS1

or S2 .... for the usb ports . all u hav to do , just to identify the port ur cell is connected to ,try changing that. keep that terminal open in which u hav run wvdial ,

it will work ..
best of luck

Hi,

I am using Openswan-2.4.10 which is running under SuSE Linux 10.1

Now I want to connect my laptop to my office network which is behind firewall (Sonicwall).

I am facing problem to create tunnel to my laptop to my office network.

I am using MOXA modem which is wireless modem (G21501) which is having SIM Card which is got from one ISP and it is connected to my laptop. My laptop is running with Openswan-2.4.10 (which is open source for VPN) under SuSE Linux 10.1

Now I am trying to connect my laptop to my office network but my office is behind firewall. So What I should do with Openswan-2.4.10 in ipsec.conf file ?

Expecting your favourable replies.
