Feature Request for Commander
|
Bruce - K5WBM
I would like to have the capability to send a command or command sequence to the radio on shutdown of Commander similar to the existing initial command.

If Commander terminates prematurely, the command might not be conveyed.

Don't know what radio you have, but many of the newer ones can be turned off via CAT control. You could program a user defined button to send whatever sequence of commands followed by the shutdown command.

Thanks for the suggestion.

I have a button programmed in commander to shutdown the radio but I was looking for a backup way to execute a radio shutdown in case I forget to execute the commander button. I am currently looking at running a bat file as part of windows shutdown. Bruce - K5WBM

I am currently looking at running a bat file as part of windows shutdown. + That won't avoid the race condition between directing Windows to send X characters via a physical/virtual COM port and directing Windows to shut down. At 9600 baud, it takes 10 milliseconds to convey a 10-byte CAT command to a transceiver; Windows could terminate its serial port device drivers within 5 milliseconds of being instructed to shut down.

That’s why 1st inquired about having Commander execute a script at shutdown.

Do you have a recommendation on the best way to automatically send a CAT command to the radio? I’m trying to make sure my K4 is gracefully shutdown before power is pulled.

That’s why 1st inquired about having Commander execute a script at shutdown.+ An "send command on shutdown" function in Commander would suffer from the same race condition.
+ Unless Windows provides a "send all of these bytes via COM port X before shutting down" function, a reliable implementation is not possible unless Commander is made the initiator of the Windows shutdown - a step I'm not willing to take. 73, Dave, AA6YQ
