Re: new PTT button seems not to work with Omni-Rig

Hi Terry
I use a SUCCI (LZ5VK) Interface: http://www.kotarov.com/projects/succi
The SUCCI interface connects to the PC via USB and to the radio via 3 connectors:
1) The CI-V (remote) connector.
2) The PTT output of the interface can be connected to either the acc1 or acc2 socket.
3) The Key jack for the CW keying output.
Normally I only use the first of these three but I can see what the other 2 ports are doing since the interface has 3 LEDS:
1) a TRX led - which blinks when data is present on the CI-V line,
2) a PTT LED which monitors the PTT output
3) a CW led which monitors the CW Keying output
so in fact I can easily see when the PTT output is active even if only the CI-V port is connected to the radio.
By the way, I spent years working with modems and RS232 interface devices in the past so I am fully aware of how the hardware aspects of all of this work
As I mentioned before, I can force the PTT line to permanently activate on the interface by changing the RTS setting in Omni-rig from "low" to "high" which makes the RTS line normally high (reverse of normal). Hence why I said before that LOG4OM simply needs to raise the RTS line on the virtual serial port when sending a PTT command to a radio / interface like mine that uses hardware PTT control.
Thanks & 73
