Hi Elliot,
The previous data was with only the address changed. Now I also changed the baud rate from 9600 to the max value 19200. That made a difference. Now the display comes alive, and I see IC-7410 in the right hand corner.
Operation is not smooth yet, frequency changes apparently get buffered and sent with a delay, so the rig frequency jumps unit the buffer is empty. S-meter works now.
