<p>Here is what I found....probably not helpful, but data points at any rate.</p>
<p>Connected to the FT-60, on download I see RTS/CTS (connected together) go high, that is important as it powers my interface. Then a good stream of data as it is downloaded.</p>
<p>On upload, I see RTS/CTS go high, then one short data burst, maybe a couple of characters, then the error pops up and data stops and RTS/CTS goes low.</p>
<p>I did one other thing, I loaded the program on my Macbook Air. I got the same results, I can read the FT-60 but not write it. I can read and write the FT-8900 on the Macbook same as on the PC.</p>
<p>It could be the Chirp software, or it could be hardware. But, as far as the hardware, it doesn't make sense that the FTB60 will work ok. </p>
<p>Suggestions anyone?</p>

<pre>That is pretty definitive, and I don't know that the o-scope will tell
you anything more at this point. It might be interesting to compare a
serial data capture from Chirp and FTB60 to see if there is a
significant difference that could explain the problem with Chirp. I
don't know how to help you with the serial capture -- I have only used
portmon on 32-bit Windows. I hear it's incompatible with 64-bit
varieties.
