USB is designed to be low cost to implement in a peripheral device, but
the tradeoff is it requires a lot of code and a fairly large amount of
CPU performance to implement for the host. A serial port just doesn't
support a high enough transfer rate to communicate with a USB device.
Therefore the PC *must* be on the USB side of the converter.

Okay, I guess that makes sense. I thought maybe everything needed to
handle the translation both ways was in the PL2303 or whatever in the
adapter. Thanks for the help.
