WBN: Restartable Server Operation for Elecraft

[Gary Johnson]

Here’s a partial solution which was mentioned some time ago: Create a .bat file that calls the utility. Here are the ones I use that launch the KPA500 and KAT500 apps and assign a baud rate, port number, and timeout. I don’t know if other parameters are possible. And I don’t know how to keep the amp from turning on at launch.  To run a batch file at startup, put a shortcut to it in your Startup folder.

rem Run the KPA500 remote control server, with parameters
cd C:\Program Files (x86)\Elecraft\KPA500 Remote\
start /MIN KPA500-Remote.exe COM2 38400 4626 500

rem Run the KAT500 remote control server, with parameters
cd C:\Program Files (x86)\Elecraft\KAT500 Remote\
start /MIN KAT500-Remote.exe COM2 38400 4627 500

Thanks, Gary. Yes, I know how to automatically start an app when the
computer powers up. And KPAxxx Remote remembers the communication
parameters that you illustrate anyway. The problem is pushing the various
soft buttons after the app starts up, most notably Start Hosting Remote and
Power (off). I think the best solution would be two tweaks to the UI: 1) an
Auto-Start Hosting Remote checkbox and 2) a Leave Amp Power Off after
Startup checkbox. (They would be separately useful although I would use
both together.)

Alternatively, they could add such parameters to the command line. (I
didn't know there were any command line parameters. I don't find them in
the KPA1500 Rev. B1 Owners Manual or the .rtf file associated with KPA1500
Remote.) Unfortunately, these programs are considered “unsupported,
contributed utilities." But I've seen them change recently, so someone is
maintaining them.
