Default Tethering 8703 using Ubuntu 7.10 and Verizon CDMA

Please Login to Remove!

I know I'm close. I've been using the tethering thread here and the "Using BlackBerry as a Modem" FAQ for more details.

I've got all the software installed and the PPP scripts set up. I get as far as sending requests to the modem, but I never receive anything back:

Initializing
ATE
Dialing
Serial connection established.
using channel 2
Using interface ppp0
Connect: ppp0 <--> /dev/pts/3
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xfa0bd154> <pcomp> <accomp>]
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xfa0bd154> <pcomp> <accomp>]
...
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xfa0bd154> <pcomp> <accomp>]
LCP: timeout sending Config-Requests
Connection terminated.
Receive serial link is not 8-bit clean:
Problem: all had bit 7 set to 0
Modem hangup


My chatscript is:


ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO DIAL TONE' ABORT 'NO ANSWER' ABORT DELAYED ABORT ERROR
SAY "Initializing\n"
'' ATZ
SAY "ATE\n"
OK 'AT'
OK 'ATDT#777'
SAY "Dialing\n"


And my ppp script is:


debug debug debug
nodetach
/dev/pts/3
115200
connect "/usr/sbin/chat -f /etc/chatscripts/blackberry"
nomultilink
defaultroute
noipdefault
ipcp-restart 7
ipcp-accept-local
ipcp-accept-remote
# added this, so that it doesn't disconnect after few mn of innactivity
lcp-echo-interval 0
lcp-echo-failure 999
modem
noauth
nocrtscts
noipdefault
novj # refused anyway, no point in trying every time
usepeerdns
user "801xxxxxx8@vzw3g.com"
password "801xxxxxx8"


Anybody have any ideas?

Thanks.

Default Got closer using wvdial...but don't think #777 is the right number

So I switched to wvdial instead of using a call script. This seems to be happier, but still not good. I'm communicating with the 8703, but #777 doesn't seem to be doing the "right thing". I'm wondering if there is something else I have to do to enable this that VZAccess does automatically under Windoze. :(


Modem = /dev/pts/2
Baud = 460800
Init1 = ATZ
Init2 = AT$QCMDR=3
Carrier Check = yes
Dial Command = ATDT
Phone = #777
Username = [email address]
Password = vzw
Sutpid Mode = 1


Any thoughts?

I have exacly the same problem with my BB 8310 (GSM, E-Plus Germany) and Ubuntu 7.10. I'm on it for a week now without any success. I'm in contact with a developer of the XmBlackBerry project, as they provided a fix for a bug in the Blackberry modems, but this is currently not working...
The problem is not in the (your) chatscript or the peer option file, but the blackberry itself, as all is working perfectly with a RAZR without changing an option.
You can go here: SourceForge.net Repository - [xmblackberry] Index of /XmBlackBerry/gprs_protocol_fix
Grab the gprs_protocol_fix.c and compile it with "gcc -o gprs_protocol_fix gprs_protocol_fix.c" and use
pty "<path to program>/gprs_protocol_fix /dev/rfcomm0" instead of /dev/rfcomm0 in you ppp peer option file. Maybe it works for you, for me it doesn't.
Maybe it's a bug in the Ubuntu 7.10's pppd or the latest device firmware for my BB. Will test it with another distribution.

PS: Using USB for modem access sometimes crashed by BB, but else it doesn't matter, Bluetooth and USB the same problems.

PS2: I tried it with Win, and USB and Bluetooth worked without any problems. So the Windows Dialer kann better handle the uniques of the BB modem... Would be interessting so see what exacly on Windows happens while dialing, but there is no console output or log file like in linux, or am i wrong?
