I was assuming the GPRS modem would respond to normal AT commands even
without the 'data plan' being added to my account. I wanted to make
sure my laptop could 'see' the modem over IR before I paid for the
service. I figured I should be able to command the modem, but the
connection would fail until I activated the service.
irdadump sees the phone and the phone is advertising modem support:
14:28:56.476387 xid:rsp ce2df4d8 < 2d5f53e3 S=6 s=4 T610 series
hint=9124 [ PnP Modem IrCOMM IrOBEX ] (28)
14:28:56.566398 xid:cmd ce2df4d8 > ffffffff S=6 s=* mypc hint=0400 [
Computer ] (25)
Anyway, I called TMobile and added the service. Within two hours, the
modem started working perfectly over IR. Somehow, the phone is
programmed to ignore modem commands until it is activated remotely.
I created a symlink from /dev/modem to /dev/ircomm0 (I don't have
another modem).
# ln -s /dev/modem /dev/ircomm0
I tested it with AT commands sent from minicom. Then, I configured
wvdial like this:
[Dialer test]
Modem = /dev/modem
Baud = 115200
Dial Command = ATDT
Init1 = ATZ
Phone = *99***2#
Password = guest
Username = guest
Stupid Mode = 1
Note: the dial string *99***2#, tells the modem to make a GPRS call
using the second (2) data account configured on the phone. The first
data account is the built-in Tmobile account.
On the phone (Sony Ericsson T610), I used the following instructions,
found in Usenet land, to configure the data account:
>From Do Sohn in news:alt.cellular.gsm.carriers.voicestream
1)go to connect>data comm.>data accounts
2)Choose New account>acount type and choose GPRS data
3)Type in new account name such as "GPRS"
4)type in the following info:
APN=internet2.voicestream.com
User ID=guest
Password=guest
5) press save
6) under data account choose the newly created account called "GPRS"
7) Note the CID number - very important since you will need to include
this in your phone dial number string later
8) select "edit" and check APN, user ID and pass word to be same as
inputed
9) select "pwd request" and choose "off" and press select
10) select "allow calls" and choose "automatic" and press select
11) select IP address and input 216.155.175.170 and hit ok
12) select DNS address and input 216.155.175.171 and hit ok
13) go to "advanced setting" and select "authentification" and choose
Works fine now. However, I am only getting about 30Kbps-40Kbps,
regardless of how strong the GSM signal is.
Does that sound line normal speeds for GPRS?
