Humm. Your suggesting that my output made it to the pl-2303, but didnt get
flushed from there to the RS232 line. I guess that makes sense.
I was thinking in terms of their not getting flushed from the driver
buffer, but hadnt thought about the dropping of the RTS line shutting
down the pl-2303 so it couldnt flush what was left in ITS buffer.
Well, if it is the hardware buffer, then it should flush in a predictable
amount of time, so my putting in a sleep before exiting the program
(closing the USB line) seems acceptble.
Thanks, I was thinking software when I should have been thinking hardware.
