BTW: The Sony CLIE site has mechanical drawings, and pinouts for most of the connectors. They also have a schematic for building your own serial cradle http://www.cliedeveloper.com/top.html
[you need to register to get to most of the mechanical details http://www.cliedeveloper.com/progra...mechanical.html
> One thing that got me thinking was that the Clie also has the USB Rx and Tx lines... Could that be used to communicate with a USB device, provided a driver was written?
I don't think it applies to the lower end SL10, but the NZ90 does have "USB host" support.
It is currently only used for printing.
ie. You can directly connect a printer to your PDA and print. Only 3 Epson models are currently supported.
BUT the UsbHost interface library is not documented. I have yet to find any public documentation on writing drivers in general.
All models of CLIE use USB for hot-syncing (ie. the CLIE is the slave, and the PC is the host/master)
