70 * This driver supports several devices devices driven by Prolific PL-2303
71 * (known also as PL-2303H), PL-2303X and PL-2303HX USB-to-RS232 bridge chip.
72 * The devices are sold under many different brand names.
74 * Datasheets are available at Prolific www site at http://www.prolific.com.tw
75 * The datasheets don't contain full programming information for the chip.
77 * PL-2303HX has the same features as PL-2303X (at least from the point of
78 * view of device driver) but is pin-to-pin compatible with PL-2303.
80 * There are several differences between PL-2303 and PL-2303(H)X.
81 * PL-2303(H)X can do higher bitrate in bulk mode, has _probably_
82 * different command for controlling CRTSCTS and needs special
83 * sequence of commands for initialization which aren't also
84 * documented in the datasheet.
