+ * This driver supports several USB-to-RS232 serial adapters driven by
+ * Prolific PL-2303, PL-2303X and probably PL-2303HX USB-to-RS232
+ * bridge chip. The adapters are sold under many different brand
+ * names.
+ *
+ * Datasheets are available at Prolific www site at
+ * http://www.prolific.com.tw. The datasheets don't contain full
+ * programming information for the chip.
+ *
+ * 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.
