You *CAN NOT* do a firmware upload via any microHAM "keyer" interface.
The K3 utility will not work with microHAM Router because it forces a
reboot of the transceiver which in turn cycles power to the interface.
Every microHAM Users Manual includes a very explicit warning about
doing firmware uploads of any transceiver using the microHAM interface.

Get a USB to serial adapter or use a plain serial port for the firmware
uploads.
