Ok, good, so 2400 baud should work.

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."

Thanks,
Johan
