* 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.
