Hi Jim; I curious, why is that? TFTP is it's own protocol, not reliant on Telnet to work. When I have PUTTY connected serially, via USB, I am still able to TFTP to my PICO W. What am I missing or did I not understand the comment? Hans ... I understood that TFTP uses udp port 69. I didn't realise that Peter has found a way to run it over serial. There is a lot I don't understand... MMEdit's file manager assumes that TFTP is usable when connected via TCPIP but not available when connected by USB. MMEdit uses the IP of the telnet connection to know where to send the TFTP packets. If you are connected by USB serial, MMEdit has no idea what the IP is or if there is any IP associated with the device it's talking to. MMBasic serial connections use raw data rather that Telnet protocol. Jim
