I need an adapter that can handle 2400 Baud to talk to the
ft639/ede639 servo controller chip or possibly a pl2303 driver
that is improved.
The pl2303-driver can handle 2400 baud, but not sure exactly what baud
rates are available for a cloned/pirated pl2303 chip (if that is what
you've got). 115200 baud should be supported, though.
We have tested different baud rates with the PL2303HX china clones.
All are working including non standard baud rates.
Ok, good, so 2400 baud should work.
Yes - this should be no problem with every usb converter.
I have different one and all of them are usable now.
But the non standard baud rates are only available with the modified
driver from Frank Schäfer.
What driver is that? The latest clone-related patch from Frank that I've
seen stated:
"According to Prolific, several (unauthorized) cheap and less
functional clones of the PL2303HX chip are in circulation. [1]
I've had the chance to test such a cloned device and it turned
out that it doesn't support any baud rates above 115200 baud
(original: 6 Mbaud) It also doesn't support the divisior based
baud rate encoding method, so no continuous baud rate adjustment
is possible."
That's a good question.
He send me a special debug version that gives all registers of the PL2303HX after the plugin.
I think it is better when Frank directly suffer us with his latest version.
