Re: Adding DSR (serial port line 6) interrupt in a Firmware Update?

[Dick Dievendorff]

If I read the KIO3-D Sub RS232 IO Board schematic correctly, pin 6 of J24
(the 9-pin RS-232 connector) is not connected to anything inside the K3. The
labeled (connected) pins are:

2 (RXD OUT)
3 (TXD IN)
4 (DTR IN)
5 (COMMON)
7 (RTS IN)

Subject: [Elecraft] Adding DSR (serial port line 6) interrupt in a Firmware
Update?

I recall that there was an email recently that the K3's internal DVR was
interrupted when the microphone or footswitch is activated to manually
transmit.
I am very interested to learn if it might be possible at the same time to
also
send an interrupt signal to the unused DSR line (serial pin #6).  This
interrupt
is used by several computer programs (TRX-Manager, Multikeyer, Voice Keyer
Express) at my station that automatically key the rig and send CW (via the
DTRor
SSB messages.

Although these programs have primarily been used here for VHF meteor scatter

schedules, they are also very handy for working contests and other band
openings.
  The K3 is of course well suited to work with any such external computer
programs
due to its built-in audio interface.  However, when the operator switches to

manually keying the K3, it would be really great if an interrupt could be
sent to
the computer programs via the serial port so that they stop their automatic
keying
of the PTT line and also stop sending audio or CW signals to the K3.  Adding
a
computer interrupt on the (currently unused) DSR line would accomplish this
and
broaden the flexibility of the K3.  Thanks for your kind consideration!

That also was what I saw....so that standard pin is currently free to have that
interrupt capability added.  Frankly, I am a bit surprised that it wasn't already
built in, since the K3 incorporates so many features to try to create flexibility
and eliminate the need for external computer interfaces.  However, I think it is
very encouraging to see that pin #6 is not currently used for some other unusual
application, and is still available for this feature to be added.  I hope that
there is some way that it can be provided.

There is no hardware available to support and interrupt
output on DSR.  It simply does not exist - no free outputs
on the MCU and no driver for the software to activate.

Why would any transceiver incorporate a full three pair
(TxD/RxD, RTS/CTS, DTR/DSR) interface if it had no need
for it?  Kenwood and the recent Yaesu rigs use RTS/CTS
handshake but I can't think of any transceiver that even
implements DTR/DSR.
