Recipe for getting Nokia 6820 working with Windows 2000/XP laptop
and CA-42 USB cable:
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.
Errors such as "hardware failure in modem" may indicate a mismatch between the physical device
and the modem software, e.g. trying to use the Nokia modem driver on COM1 RS232 port.
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.
You will not now be able to access the phone as a network modem, because the
port is in use by the PC Suite software. The PC Suite application does not contain a network modem or
dialler; it is for transferring data to and from the phone itself.
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 "hardware failure in modem" may indicate a mismatch between the physical device
and the modem software, e.g. trying to use the Nokia modem driver on COM1 RS232 port.
Errors such as "modem not available" may indicate that the modem is in use by other software
such as PC Suite.
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.
IM+ text version
from shapeservices.com (about $20 US)
works on the 6820 and supports a number of instant messenging protocols.
There's a free trial version. Traffic seems to go via shapeservices proxy gateway.
In Jabber, it seems to support IM only, not chat.
