Modbus slave serial problems #4

I've found the following problem:

set up uc in eva ics 3.2.0 as modbus slave on serial port
send a garbage to the port
controller modbus slave stops responding until restarted

I was able to reproduce this issue, yes, unfortunately it's a bug of pymodbus library. It seems to be fixed in 2.2.0 however since 2.2.0 isn't released yet, the only way is to build it from sources:

https://github.com/riptideio/pymodbus/releases/tag/v2.2.0rc4

we'll set pymodbus 2.2.0 in install requirements as soon as it will be released.

pymodbus 2.2.0 released today. please update to EVA ICS build 2019041801 which contains it. the issue is fixed now
