I even sold my Frankenstein's monster C2N232 (an early prototype that
I extended with serial bus support).  But I have one C2N232 left, which
I could use for testing c2nload.

Good news: I managed to work around some bugs of USB to RS-232 adapters.
Adapters based on the Prolific PL-2303 should now work on GNU/Linux and
Windows, and adapters based on the FTDI FT232 should work on Windows XP.

The Linux ftdi_sio driver doesn't seem to implement any flow control, or
even tcdrain() or a properly blocking write().  The driver has not been
updated for some 2 years.  I guess most FT232 users are only using it
for receiving data, which should work better.

The Linux pl2303 driver works with CTS/RTS handshaking only.  On Windows,
both adapters work with XON/XOFF handshaking.

I will release new versions of the software as soon as I get a chance to
test it with a C2N232I.
