[Elecraft] Firmware upload problem

[Joe Subich, W4TV]

Setting "No radio" does not guarantee transparent operation 
by microHAM Router.  Again:  

   DO NOT PERFORM A FIRMWARE UPLOAD USING MICROHAM ROUTER 
   WITH ANY MICROHAM INTERFACE.  NO EXCEPTIONS.  

Even though I know my way around Router and the microHAM 
interfaces well enough to generally make sure Router is 
transparent, there is no way to force and lock the data 
rate between the microHAM interface and the transceiver. 
I keep a serial cable attached to a serial port on one of 
my computers specifically for use when updating K3 firmware. 

73,
