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<cr> .. does actually key the transmitter in
CW mode equivalent to a key closure. I did verify operation of *TK
and /<char><CR>.
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.
