So dug up the old adapter, chipped the rubber housing away and soldered some wires directly on the pins to get the to the TTL signals. Basically it meant that the baud rate had to be changed in the middle of the operation from 19200 to 57600, on TTL levels. However I needed to flash some board that needed 'variable baud rate' which the BP could not do. But I haven't had to use it lately since I mostly use my BusPirate. On-topic, I have a fake(?) serial adapter bought probably 10 years ago, same PL2303HX chip. But the FT232 costs a lot more than a PL2303.

c) What's the point in cloning a cheap rubbish IC that is plagued for years by driver problems? Wouldn't you clone something where you would actually benefit from working drivers from the original manufacturer? And just when they had another persistent driver failure they suddenly started claiming it is about face ICs. Or for a long time the installer as such didn't work. Like their installer trying to replace a standard windows sys driver with some version they probably lifted from an ancient hacked Asian version of Windows, breaking the driver. b) Prolific never managed to get their Windows driver development under control. Knowing the source and age of my cables I can't believe this. Every single one of them refuses to work with recent drivers under Windows 7 and XP and report error 10.

Some very old, long before Prolific talked about fakes.

I have a good number of PL2303-based adapter cables.
