Nokia 6820 + Internet

From the Nokia support site, install either the CA-42 software driver or the PC Suite. The PC suite package appears to contains the cable drivers. I think. At least, if you install the cable driver first the PC suite install says it is uninstalling software, then reboots, then installs the drivers.

If you install just the CA-42 software driver, you will be able to use the phone as a digital modem.

CA-42 Driver only

• Unplug phone
• Run install program for CA-42 cable drivers
• May have to accept unsigned drivers. If the install seems to hang, there may be a dialogue hidden behind the blue splash screen; it can be resized or moved aside.
• Plug in phone. Phone indicates "data enhancement connected".
• USB devices should be detected, and drivers installed for phone and USB parent. Takes ages on 400MHz P3.
• Go to Control Panel. Enter Phone and Modem Options. Click "Modems" then "Add"
• Check "I will select from a list"
• Click "Properties" and set the manufacturer to "Nokia" then the type as "6820 cable".
• (In Device Manager - from Control Panel/System - e.g. COM10 should show as working)
• Click "Diagnostics". Hardware ID should be e.g. "mdmgen96"
• Click "Query Modem". It should connect and log various AT commands, along the lines of

    Modem type: Nokia 6820 Cable
    115200,8,N,1, ctsfl=1, rtsctl=2
    Initializing modem.
    Send: ATS0=0
    Recv: OK
    Interpreted response: OK
  

  If it does not, disconnect the phone, reconnect, and try again.
• From e.g. "My Network" create an instance of a dialup connection
• In the dialer properties, set the dialled number to "*99#" (for Rogers Wireless)
• Use a blank username and password
• Open the dialler. The phone should connect.

PC Suite

• Unplug phone
• Install the PC Suite software. Accept the warnings for unapproved software
• Plug in the phone. Phone indicates "data enhancement connected".
• USB devices should be detected, and drivers installed.
• At completion, PC Suite should start; status line indicates "phone connected"
• "Transfer Files" should include a folder "Nokia 6820" which shows the contents of the phone
• "Manage Connections" should show a checked box for "serial cable (CA-42)" with properties e.g. COM10.

Network Modem with PC Suite

• In PC Suite, "Manage Connections", uncheck the serial cable box and click OK.
• Status line changes to "phone disconnected" (although the cable is still connected)
• Unplug phone then reconnect it
• Go to Control Panel. Enter Phone and Modem Options. Click "Modems" then "Add"
• Check "I will select from a list"
• Click "Properties" and set the manufacturer to "Nokia" then the type as "6820 cable".
• (In Device Manager - from Control Panel/System - e.g. COM10 should show as working)
• Click "Diagnostics". Hardware ID should be e.g. "mdmgen96"
• Click "Query Modem". It should connect and log various AT commands, as above under "CA-42 Driver only". If it does not, disconnect the phone, reconnect, and try again.
• From e.g. "My Network" create an instance of a dialup connection
• In the dialer properties, set the dialled number to "*99#" (for Rogers Wireless)
• Use a blank username and password
• Open the dialler. The phone should connect.

Errors such as "modem not available" may indicate that the modem is in use by other software such as PC Suite.

Debugging PPP

netsh
ras
set tracing PPP enable

Rogers seems to support PPP and CHAP but not MS-CHAP or MS-CHAP2, and not encryption. The default selection (EAP?) seemed to work OK, though. I only turned on logging to try and understand why Windows was working and Linux wasn't.
