I have a problem connecting my Ericsson T39m via BlueTooth/USB (which apparently work as serial port connection).
The phone was bought second-hand, with no CD, etc, so I don't have any accompanying software, including drivers to set it as a modem. Downloading XTND from Ericsson site didn't help, either. It did not detect the phone, and I had problems uninstalling it afterwards (installshield was crashing, so I had to clean it out manually).
I have no slightest problems via IR link, but it is too clumsy. To use phone as a modem on the move, I have to tape it to external IR adapter :)
I primarily need to use it on notebooks running Win XP Pro/Corp and Win 98 SE/PanEuro.
If all else fails, I could grab a different phone, but I'd hate to because I am too accustomed to this one, and damn it, I never seen another that could live for over two weeks on one charge... :)
