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