Can PropStick DB9 be used as a Serial Port
Can the Serial port only be used for programming or can it be a general Serial port I can access at runtime?
Scenario would be:
Attach the serial port to my computer.
Launch the Editor and program the propeller chip.
Quit the Editor.
Reset the Propeller chip.
Launch Hypterminal to send commands to the running program.

You might use a MAX3232 to avoid such with a generic RS-232. The Reset on that [noparse][[/noparse]see the PropSTICK] documentations, is separte.· Of course, you can simply buy a PropSTICK to do the job.
Since the Propeller is somewhat '5volt tolerant',· you might use the MAX232, but you would have to provide +5volts to it while inserting resistors to reduce the peak TTL/CMOS from 4.8V to optimally 3.3V.·
[noparse][[/noparse]This gets a bit complicated and nobody had really do it yet.· Are you into exploring?]
