Hello everyone.

Although due to the architecture of the BasicStamp I understand 
why RS-232 was used on the PSIM initially, but it's not a huge 
task to incorporate a USB port .  I did a post search and noticed 
that it's come up here.  Has there been any further thoughts on 
this?  Did the idea go anywhere? I would think a USB to be 
preferred , as it interfaces more readily with a larger number of 
systems - i,e, Macintosh. I've tried using RS232 plotter on a PC 
cad program while running Virtual PC on a Mac via a USB/232 
adapter cable and the results were pretty dismal.
