Hi EbNaut

I'm using Ebnaut Sender V0.8 for windows to send the messages. It uses the =
DTR+DSR lines in a COM port
to key the BPSK modulation in the PA

So far, so good. But what about the carrier control (PTT) ?. The software d=
o not control this and I must be
aware to turn the transmitter ON before message starts and turn it OFF when=
 finished. This is even more
complicated if you plan repeated transmissions overnight and not left the t=
ransmitter permanently ON
between messages, blocking the channel to other users

Before paralleling another tool to schedule the PTT I wonder if Paul may im=
plement this. May be using a
different COM for the PTT or just adding an option to use DTR for BPSK and =
RTS for PTT in the same COM

I asked a friend to have a look to the source code and modify it, but seems=
 there are libraries not provided
to compile it for windows

Any comments wellcome. May be I'm missing an easier way to do this
