Yeah, but the most common application seems to be USB-RS232, and to emulate
a com-port.
For those that don't have a comport.


One thing though, this type of emulation drives me nuts, I have a number of
commercial stuff based on the fdti-chip, emulating com-ports, and it seems
to change com-port each time it's used, its very frustrating.
