Hi Mal
What ever you do you will need to make something.
A/ Your best bet is to buy a serial to USB adaptor and then a pair of switching
transistors one to key the tx through the key hole of your tx. If you are not
using break in then the other transistor is need to switch the trx from tx to
rx and visas versa.
B/ If your software only produces a cw audio tone for ssb rigs then you will
need to make a simple amplifier and tone detector.to 1/ switch the trx from rx
to tx with a bit of delay to allow for inter dit spaces and 2/ key the tx
through the aforementioned key hole with out a delay so it tracks the keying of
the tone precisely.
There are probably other ways to do it like yet again buy a serial card to pop
in your PC or even a parallel card you still have to build a simple transistor
switch for the one or two functions described above. I am sure you can buy the
whole kit and caboodle to do what I have described .but I don't know where
from. However construction is very simple for us Radio Amateurs. The schematic
is usually found in the "Help" files associated with the software.
Hope this helps!!

MFMy computers do not have a
RS232 serial port and I needed an alternative method to
generate and key my SSB transceivers in QRSS mode.The method used is SPECLAB
to
generate an appropriate tone , in my case 700 Hz, which
keys the TX in SSB MODE.Ideal method for any SSB
transceiver or Transverter using VOX, no hardwire switching
needed.I do not have
a USB/SERIAL port adaptor which of course is another
method but needs a hard wired line between computer and TX
for keyingOthers may
already be using this method but I have not seen any
details on the subject
