Reliance ZTE MC315+ on Ubuntu Feisty 7.04 also on BOSS 2.0 (debian sid/testing, kernel 2.6.21-1-486, gnome 2.18)

Finally, It Works !! :-)

I struggled a lot to make it work on my Ubuntu on IBM LEVONO 3000 N100 Model 0768.

No Sucess :(

it used to stop at ;

--> WvDial: Internet dialer version 1.56
--> Initializing modem.
--> Sending: ATZ
--> Sending: ATQ0
--> Re-Sending: ATZ
--> Modem not responding.

But finally it WORKED !! Thanks to Manoj.

Here's HOW:

1. Now my dmesg says (after inserting a card in pcmcia slot);

[ 2713.564000] pccard: PCMCIA card inserted into slot 0
[ 2713.564000] pcmcia: registering new device pcmcia0.0
[ 2713.612000] ttyS3: detected caps 00000700 should be 00000100
[ 2713.612000] 0.0: ttyS3 at I/O 0x2e8 (irq = 3) is a 16C950/954

2. /etc/wvdial.conf is ;

[Dialer Defaults]
Modem = /dev/ttyS3
Baud = 57600
SetVolume = 0
Dial-AT-OK ATDT Command =
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
Phone = #777
Username = xxxxxxxxxx
Password = xxxxxxxxxx
New PPPD = yes
Carrier Check = no
Stupid Mode = 1

3. As a root:

setserial /dev/ttyS3 baud_base 460800
wvdial

--> WvDial: Internet dialer version 1.56

--> Sending: ATZ
--> Sending: ATQ0

5. Once all set look into /etc/resolv.conf which normally in ubuntu gets generated automatically by NetworkManager

nameserver 202.138.97.193
nameserver 202.138.96.2

# Note: If not, edit it manually, add primary and secondary DNS with reference to point 3 above.

6. root@priti-laptop:# nslookup google.co.in
Server: 202.138.97.193
Address: 202.138.97.193#53

Non-authoritative answer:
Name: google.co.in
Address: 72.14.207.104
Name: google.co.in
Address: 72.14.235.104
Name: google.co.in
Address: 72.14.203.104


# Note: i) With the value of baud 57600 in /etc/wvdial.conf, keep changes the value of baud_base as "n*baud " with `setserial` where n is 2,4,8,16

ex. baud=57600, baud_base=115200,230400,460800 ....

for baud_base 460800 or 921600 modem will start responding but may vary OS to OS.


ii) One can play with UART and baud_base together, if above doesn't work.


iii) Troubleshoot with Reliance ZTE CDMA 1X MG880 ?
