Hello everyone,

Got a question here. Is there a cheaper way to connect the serial
port (9 pin) to the USB port? I've heard about the BAFO but it's
quite expensive though. Any alternatives?

Pls reply ASAP. Thanx in advance!

    Hello,
    Unfortunately, the connection requires more then just electrical
    interface. There is also the buffer and driver interface required.
    Unless you built your own out of a Usb to serial driver chip, I don't
    believe it can be done easily.

    $20.00 is expensive? From LOTS of research
    into USB to serial ports, the BAFO is one of
    the least expensive -- that's as good as it
    gets, I'm afraid. You could look it up on
    www.nextag.com to find a lower price...
