[Orion] Orion PTT Question

[BarryG]

Appreciate the comments.  I wonder if I'm mis-stating my question.  The contest logging programs actually call the function "PTT via comm port" but perhaps it should really be viewed as "MOX via comm port".  I believe all the software does is put the rig in transmit mode.  The Orion has commands to "key" (TK)and "unkey" (TU) the transmitter.  Perhaps this will accomplish the "PTT via comm port" function.

Barry ...

It does not appear to. You can send characters, which will key the 
transmitter up for each character -- as though you had simply keyed 
it using the internal keyer. And you can key the transmitter. The 
"key" command ... *TK .. does actually key the transmitter in 
CW mode equivalent to a key closure. I did verify operation of *TK 
and /.

But there does not appear to be a soft command to do the PTT 
function as it has been discussed (if you can actually call it a 
discussion) on the tentec list -- at least I haven't found it. 

I did just post a note over there of a very simple means of doing the 
PTT thing if you have a QSK amp with handshake, but it does 
require a hardware open collector PTT interface that pulls low to 
invoke.
