No, the USB differs slightly. To send a get version command on the
serial you send 0x02 0x48. On the USB it's 0x02 0x02 0x48, the first
0x02 is the number of bytes being sent. That are a lot of other
little details you need to know. Once you work around them you can
write a routine to deal with it.

With the USB & Serial port version they can be asynch (as I understand
it). That would be like X10, to take proper advantage of the protocol
you should wait for ACK, NAK or lack (lack of response).

I don't have the HDK yet (I'll order that in a few months, when I
get time).
