I have a G5 and an old MessagePad 2100.
I have been unable to install packages by any means. I've tried NewTen and Escale, with both a Keyspan serial adapter and a Farrallon ethernet/phonenet bridge.
The serial adapter won't connect at all. The Farrallon Bridge will dock via Escale, and the 'keyboard' connection works, but transferring packages never gets anywhere - the progress bar never moves.
Any ideas anyone?
