Also, thanks to Paul for this, on Palm you need to create the connection:

* Palm t3, latest firmware patch.
* prefs
   * bluetooth options
        -> choose a name for your palm (your hotsync name is good)
        -> trusted devices
        -> find the PC and pair with it
   * connections  (http://howto.pilot-link.org/bluesync/eb.html)
        -> create a new connection
        -> set the following options
            Name: "btcon linux"
            Connect to: PC
            Via: Bluetooth
            Device: [your PCs BT trusted device name]
                -> Details
                   speed: 115,200 (probably irrelevant)
                   flow ctl: automatic
   * network (http://howto.pilot-link.org/bluesync/ec.html)
        -> create a new service
        -> set the following options (name MUST be different
        from the "btcon" name!)
            Service: btnet linux
            User name: blank
            Password: [prompt]
            Connection: btcon linux
                 -> Details
                    Connection type: ppp
                    Idle timeout: never
                    Query DNS: [checked]
                    IP address: [automatic]
                    -> script
                        just says "End:"

* install the WEBPRO browser off the PalmT3 disk.
* also recommended, the brilliant freeware "bluefang" program which will
allow you to automatically enable and disable bluetooth when certain
applications run.
