Ok, sorry for that, I made the wrong assumption that your /dev/ttyUSB0 
device didn't even exist and that it was the reason you could not have 
any access to it.

This is quite strange as (at least as far as I know) PL2303 chips 
usually cope quite well with flow control. I've been using quite a few 
of them here, but never on Fedora Core however (thought I doubt this 
makes any difference here).
