LM5 3rd RS485 port does not work for Modbus

[Andrey Esaulov]

LOG:
string: 1080 /usr/bin/luajit /dev/ttymxc2

Try disabling modbus mapper and reading data via a script with debug enabled, then post what you get.
See this post for more info: https://forum.logicmachine.net/showthrea...2#pid16012
You will need to change port name and optionally serial port settings, slave id and which registers to read.

Also run this script and post the result to make sure that only one process is using the port:

Code:

data = io.readproc('lsof | grep /dev/ttymxc2')
log(data)
