Actually, adapters that use the FTDI FT232 [...].
Drivers are also
not an issue.
Well, it depends. Provided the host you're connecting them to is one
of the major, or even middling-to-large minor, OSes, you're probably
OK. But as far as I can tell there is no documentation on the
host-to-chip interface except for existing driver code; the Linux and
NetBSD drivers include comments indicating that they were written based
on direct assistance from FTDI staff rather than from documentation.
So if you're doing something unusual, like trying to use them from the
bare metal, or with an experimental fringe OS - basically, something
not big enough to get FTDI's attention - you may be better off with a
chip that implements the async serial device class, which _is_
documented, instead.
