I have the same issue with royal TSX (had the same problem with terminus when trying to rule out royal TSX). Oddly enough, if I add an external connector and enable telnet on the VTY ports, the issue disappears. It seems to be specific to the break...
I use something like https://buy.serialio.com/products/bluesnap-bluetooth-2-1-to-rs232-adapter. Works fairly well, no software required, but I do believe I had to adjust some jumpers on the device.
You can always cancel with reload cancel. But reload at you can specify a time to reload, reload in you could say 5 minutes etc, and cancel if not needed if that is what you are asking.
