Folks, for posterity (and hoping someone can help), here's some info on getting through to XSY-AT* VFD using Modbus ASCII protocol: https://www.chipmaker.ru/topic/21809...omment=4791765

I've written a little python program, but so far I've got only random garbage back (padded with lots of zeros) from the serial port, regardless of what command I send and baud rate used. The VFD works fine using panel controls.

# send the "jog" command
# ./send-cmd.py '3A 30 31 30 36 32 30 30 30 30 30 30 33 44 36 0D 0A'
ascii: 3A 30 31 30 36 32 30 30 30 30 30 30 33 44 36 0D 0A hex: bytearray(b':010620000003D6\r\n')

Hope someone has figured it out and can help..
