From manual.....

The JZ20 built-in USB port may be used for programming. Add-on Modules are available
by separate order for communication and cloning. Note that the USB port and an Add-on (RS232)
module cannot be physically connected at the same time

Then you must check connection via info mode...

kratmel thanks!

i use the mj20-rs rs232 communication module.
the problem was i didn't cross rx and tx in the d-sub.

maybe I had to cross it because I use a weird usb-to-rs232 with female end instead of the regular mail d-sub at the end.

and " check connection via info mode... " is a good advice

anyway this code is working 😀
