|

*
|
|
* 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
|
