 * fit2.c is a low-level protocol driver for the older version
 * of the Fidelity International Technology parallel port adapter.
 * This adapter is used in their TransDisk 2000 and older TransDisk
 * 3000 portable hard-drives.  As far as I can tell, this device
 * supports 4-bit mode _only_.
 *
 * Newer models of the FIT products use an enhanced protocol.
 * The "fit3" protocol module should support current drives.
