Serial interface
I have set up a Propeller to serial port circuit as seen in
http://www.parallax.com/Portals/0/Downloads/docs/prod/prop/SerialtoPropeller.pdf
I then connect the serial plug to a Radioshack 26-183 USB to serial cable.· When I search for the propeller chip using the Propeller Tool V1.2, it cannot identify the presence of the propeller chip.· It does, however recognize the Radioshack USB to Serial cable.· I have the Radioshack USB to Serial cable settings as follows:
Bps:· 9600
Data bits:· 8
Parity:· None
Stop bits:· 1
Flow control:· None
Any thoughts about what I might be doing wrong?
Thanks.

we designed and built a module to be mounted
in any circuit that requires the conversion USB/232:

The interface·is USB/TTL 5 volts, we must adapt the signal at 3.3 volts)
