modbus-serial, serialport and jsmodbus
The serialport optional dependency is just to list all ports on your system in the client configuration.
It is not the serialport version to work with Modbus at runtime.
For that check the modbus-serial or jsmodbus package.json, please!
The modbus-serial supports and works for TCP connections in that package, too.
The jsmodbus package is just to provide a simple Modbus Server node.
All Modbus commands running on modbus-serial.
TCP or Serial testing
If you get in trouble with TCP connections, then check and test with just modbus-serial first, please!
If you get in trouble with Serial connections, then check with just serialport first, please!
