Does the head have some kind of RS-232 serial port connection on it so

No
It would be nice if it did. As long as the main radio body had one
also.
Which of course the main body does but again the Head does not.
Let us hope we never witness the "Silence Of The Hams"

I'm really puzzled now. If the TNC is in the control head, and the
710 supports the same kind of "packet mode" operation as the 700 with
an external computer/terminal, then there must be some way TNC data
is getting to the main chassis where the serial port connector is
located. <br>
<br>
<br>
Is it interleaved in the data stream carrying radio control functions
(volume, squelch, channel,etc.) from the head to the main chassis? <br>

<br>
Or perhaps separate TTL-level signals in other conductors of the
head-to-radio cable with conversion to true RS-232 levels inside the
main chassis?<br>
