* Simple datasheet

* (english)
|
||||
* 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.
