Thanks Josh.  Being new to the "102-Windows" world, I just adopted the
parameters in the Telcom manual.

I just tried a different serial to USB cable with the same null modem
adapter I used before.  This time Windows doesn't even recognize the
insertion of the cable in the laptop.

Regarding Prolific:  I used the driver that came with the original
serial/usb cable.  It was provided by Prolific, so that's why I'm using
that driver.  As today's cable isn't recognized by Windows, I don't know
what driver to use, or just keep plugging away on the Prolific driver.

When people say they've had poor luck with Prolific, are they saying with a
Prolific cable?  or with a Prolific driver?
