Can anyone provide up-to-date tips on connecting to Verizon Wireless' EVDO service? My hardware is an IBM/Lenovo T61p, and the failure would seem to be somewhere in the pppd call peer scripts and chat.

Kernel parameters look good:
| Code: | # grep -e "PPP\|SIERRA" kernel-config-x86-2.6.28-gentoo-r1
CONFIG_PPP=m
# CONFIG_PPP_MULTILINK is not set
CONFIG_PPP_FILTER=y
CONFIG_PPP_ASYNC=m
CONFIG_PPP_SYNC_TTY=m
CONFIG_PPP_DEFLATE=m
CONFIG_PPP_BSDCOMP=m
CONFIG_PPP_MPPE=m
CONFIG_PPPOE=m
CONFIG_PPPOL2TP=m
CONFIG_USB_SERIAL_SIERRAWIRELESS=m |
Normally only module ppp_generic autoloads, so modprobe ppp_async:
| Code: | # modprobe ppp_async
# lsmod | grep -e "ppp\|sierra"
ppp_async 7424 0
crc_ccitt 1984 1 ppp_async
ppp_generic 17756 1 ppp_async
slhc 5184 1 ppp_generic
sierra 8776 0
usbserial 23812 1 sierra
usbcore 115032 9 sierra,usbserial,sl811_hcd,usbhid,ohci_hcd,uhci_hcd,usb_storage,ehci_hcd |
The Sierra modem is found on the USB bus:
| Code: | # lshw | grep Sierra
product: Sierra Wireless MC5725 Modem
vendor: Sierra Wireless, Incorporated
# lsusb

The appropriate /dev/ttyUSB0 note already exists:
| Code: | # ls -l /dev/ttyUSB*
crw-rw---- 1 root uucp 188, 0 Jan 20 17:47 /dev/ttyUSB0
crw-rw---- 1 root uucp 188, 1 Jan 20 17:47 /dev/ttyUSB1
crw-rw---- 1 root uucp 188, 2 Jan 20 17:47 /dev/ttyUSB2 |
Per the thinkwiki reference, I can echo some test interactions with the modem:
| Code: | # cat /dev/ttyUSB0 &
[1] 18512 |
| Code: | # echo AT > /dev/ttyUSB0
AT
OK
|
| Code: | # AT+GSN
0x6SNIPMYHEX
OK
|
The /proc interfaces work to turn on and off the modem via software:
| Code: | # echo enabled > /proc/acpi/ibm/wan
# echo 'at!pcstate=1' > /dev/ttyUSB0
# at!pcstate=1
OK
|
(Omitting 'disabled' step, but that works too)
Now for the part that doesn't work, pppd call (script). For any variation of the following I get a nondescriptive "Connect script failed."
I've tried the thinkwiki version verbatim:
| Code: | # cat /etc/ppp/peers/vzwconnect
noauth
#your login information
user SNIPMYNUMBER@vzw3g.com
connect "/usr/sbin/chat -v -f /etc/ppp/peers/vzw_chat"
defaultroute
usepeerdns
ttyUSB0
# "speed 3686400 not supported"
230400
local
usepeerdns
debug
-detach |
| Code: | # cat /etc/ppp/peers/vzw_chat
' ' 'ATZ'
'OK' 'ATDT*99#'
'CONNECT' |
And a version that I think may have come from Gentoo Wiki before the data loss. It could be pppconfig generated, but if it were, I would have expected references to /etc/chatscripts instead:
| Code: | # cat /etc/ppp/peers/verizon
#the USB serial device of the EVDO PCMCIA card.
ttyUSB0
#your login information
user SNIPMYNUMBER@vzw3g.com
230400 # speed
debug
defaultroute # use the cellular network for the default route
usepeerdns # use the DNS servers from the remote network
-detach # keep pppd in the foreground
crtscts # hardware flow control
#lock # lock the serial port
noauth # don't expect the modem to authenticate itself
connect "/usr/sbin/chat -v -f /etc/ppp/peers/verizon-connect"
disconnect "/usr/sbin/chat -v -f /etc/ppp/peers/verizon-disconnect" |
| Code: | # cat /etc/ppp/peers/verizon-connect
#time out is 20 because sometimes the card takes a little while to initalize
TIMEOUT 10
ABORT 'BUSY'
ABORT 'NO ANSWER'
ABORT 'NO CARRIER'
SAY 'Starting Verizon\n'
'' 'AT'
'OK' 'ATQ0V1E0'
'OK' 'ATZ'
'OK' 'AT&F'
# Dial the number
SAY 'Connecting...\n'
'OK' 'ATDT#777'
CONNECT CLIENT
# cat /etc/ppp/peers/verizon-disconnect
"" "\K"
"" "+++ATH0"
SAY "Disconnected from Verizon." |
Any suggestions would be greatly appreciated. Unfortunately I can not (easily) reinstall Windows XP or Vista in a dual-boot setup to test or confirm activation of this modem. I was activeated and online Verizon Wireless under Windows Vista Home Premium on the day I got the machine, but the modem has stayed idle since that day.
Thanks again. |
