I have read this is a problem with the jssc library and the chinese arduino boards. With a different usb serial adaptar (ch340).
I have tried with an arduino original and it works.
The Arduino ide detects both because, i thing, it use a different versión of the jssc.jar (jsscarduino.jar???)

Hi, I have the same problem.
I can´t use the menu in the 128×64 display. Do you know something new?
Which lcd could I use to fix it?

[jesus zalba]

sorry but it doesn’t work.
The name of this port is:
/dev/cu.wchusbserial410

and I can see this

ls -l /dev/cu.wchusbserial410
crw-rw-rw- 1 root wheel 17, 9 4 dic 16:46 /dev/cu.wchusbserial410

and with the terminal in arduino soft works fine:

HELLO WORLD! I AM ZARPLOTTER #0
Firmware v10
Built Dec 4 2020 16:45:21

As well as the following G-codes (http://en.wikipedia.org/wiki/G-code):
G00,G01,G02,G03,G04,G28,G90,G91,G92,M18,M100,M101,M114
Has LCD

Hi, I know what is the problem but I don’t know how can I solve.
I tried to connect with ‘universal gcode sender’ and it had the same problem but if you write the name of the port in the selection list it is able to connect with the arduino.
The problem is in the communications library, it does not recognize all port names.
So I think you can solve the issue if you put a text area where we can write the port name.

The real problem, I think, is the serial chip in some arduino boards. If the serial port is named like the standard there is not problems.

Thanks a lot.
