I hope it has a suitably fine tip, otherwise it's back to Bill's TTL 
version of the modifications!

The Sure Electronics unit works directly plugged into a serial port with 
USB for power only.  I have not found any need to alter any of the 
parameters you mention - it just sits there and works.

With respect, I suggest getting the unit working in basic serial mode 
first, and only then trying to do the more complex things.  Bill has 
pointed you to the manual, and there are download details and screen-shots 
about modifying the serial baud rate on my Web page:
