16: === WWAN access using PPP and usbsacm driver ===
17: 
18: ==== Background ====
19: 
20: Many WWAN modems are essentially USB modems. The standard for USB modems is called Communication Class Device Abstract Communication Model (CDC ACM). Popular PCMCIA WWAN modem cards, such as Novatel Merlin V620 and Kyocera KPC650, include an internal USB controller and a CDC ACM device - and can use the same drivers as the USB modems connected to the external USB ports.
21: 
22: The Solaris //usbsacm// driver supports devices compatible with CDC ACM. The following instructions were verified with the Novatel V620 EV-DO modem card from Verizon, previously activated in the VZAccess software for Windows.
23: 
24: ==== Configuration ====
25: 
26: Connect your modem device. After a few seconds, one or more devices numbered 0..N should appear in the /dev/term directory. At the software level, these devices behave just like serial ports, even though the data flows over USB. You can use any existing serial communication software like PPP or terminal emulators. If device does not appear in /dev/term, see the [[Troubleshooting>>#usbsacm_troubleshoot]] section below.
27: 
28: These instruction assume /dev/evdo to be your device. Typically you’ll need to create a symlink to /dev/term/0:
29: 
30: {{code}}ln -s /dev/term/0 /dev/evdo{{/code}}
31: 
32: To configure PPP, you can use these files as a starting point:
33: 
34: * [[evdo>>attach:Project wwan.files@evdo]]: put in /etc/ppp/peers directory
35: * [[evdo-chat>>attach:Project wwan.files@evdo-chat]]: put in /etc/ppp directory
36: 
37: Edit the "user" entry in the [[evdo>>attach:Project wwan.files@evdo]] file, e.g. Verizon users should replace 1234567890 with their phone number.
38: 
39: Now run:
40: 
41: {{code}}pppd call evdo{{/code}}
42: 
43: and watch the output. If it fails, retry a couple times before starting [[troubleshooting>>#HTroubleshooting]]. Successful PPP connection is accompanied with a message "Serial connection established." and {{code}}ifconfig -a{{/code}} will show the sppp0 interface. You might need to copy /etc/ppp/resolv.conf to /etc/resolv.conf and /etc/nsswitch.dns to /etc/nsswitch.conf to get your name resolution right, or use something like [[inetmenu>>Community Group laptop.inetmenu]]. The WWAN should be fully accessible after that.
44: 
45: ==== Troubleshooting ====
46: 
47: ==== Binding the driver to the device ====
48: 
49: If no device appears in /dev/term, run ’prtconf -D’ and locate your modem device in the output, e.g.:
50: 
51: {{{
52:         pci1025,57, instance #0 (driver name: pcic)         &#x3c;~--- PCMCIA controller
53:             pcs, instance #0 (driver name: pcs)
54:             pci1033,35, instance #0 (driver name: ohci)     &#x3c;~--- internal USB controller
55:                 device, instance #0 (driver name: usbsacm)  &#x3c;~--- modem device
56: 
57: }}}
58: 
59: If the "device" node does not show a driver name associated with it, you can try to //bind// the driver to it. To do this, locate your device again, this time in the ’prtconf -v’ output (e.g. search for "device,"):
60: 
61: {{{
62:                 device, instance #0

92:                             value=00000002
93: 
94: }}}
95: 
96: The ’compatible’ property is what you are looking for. Choose one that looks like "usbXXX,YYY", where XXX is vendor ID and YYY is product ID. Run run the following command:
97: 
98: {{code}}update_drv -i "usbXXX,YYY" usbsacm{{/code}}
99: 
100: After reboot ’prtconf -D’ should show usbsacm driver next to the device. If not, the driver failed to attach, probably not recognizing the device as compatible.
101: 
102: ==== Testing modem connection ====
103: 
104: A simple way to test your modem is to send it some simple commands using tip(1) or other terminal emulator:
105: 
106: {{{
107: # tip /dev/term/0
108: connected
109: **atz**
110: OK
111: **ati**

113: Model: CDMA MERLIN V620

121:

123: **atdt#777**
124: CONNECT
125: 
126: }}}
127: 
128: Characters in bold font are user input, the rest is modem output. at+csq shows signal strength on this particular modem. Dialing #777 usually gets you on the service provider’s network - if the modem returns "NO CARRIER", it could mean weak signal or refused connection from the network.
