@anon65719490,

I used an example from github demo-rtu.lua with minor mods, but /dev/rs485 nor /dev/ttyHS0 works.

root@TRB145:~# lua demo-rtu.lua
using libmodbus runtime version:        3.1.6
using lua-libmodbus compiled against libmodbus:         3.1.6
byte timeout:   0       500000
response timeout:        0       500000
Opening /dev/rs485 at 9600 bauds (N, 8, 1)
lua: demo-rtu.lua:14: Couldn't connect: No such file or directory
stack traceback:
        [C]: in function 'error'
        demo-rtu.lua:14: in main chunk
        [C]: ?
