The HP 95LX supports file transfers in the DataComm application. Both Kermit and Xmodem transfer protocols are provided on the HP 95LX. If you have software on the Macintosh that transfers files using either of these protocols, you only need the cable to connect to the HP 95LX. The cable can be ordered from your HP dealer by specifying part number HP 82223A.
Some third party products have been developed to provide the Macintosh -- HP connection. Sparcom and DataViz have solutions advertised in The HP Palmtop Paper.
