+ *
+ * Datasheets are available at Prolific www site at

+ *
+ * PL-2303HX is probably programmed the same as PL-2303X.
+ *
+ * There are several differences between PL-2303 and PL-2303(H)X.
+ * PL-2303(H)X can do higher bitrate in bulk mode, has _probably_
+ * different command for controlling CRTSCTS and needs special
+ * sequence of commands for initialization which aren't also
+ * documented in the datasheet.
