Hi,
Trying to configuring a ISR4331/K9 with PuTTY using COM4 (usb to serial). in elevated mode (#), gets an error "This command is not supported" while trying to write to memory or copy to start up config or even config t. A reload (soft boot) managed to fix the issue (this is how a config file is pushed to the router) but now a reload is not an option since then missing the config. So ideas? (the device is brand new). IOS Version 16.9.4.
