error event is not triggering

`
 client.on("error",console.log); // the error event is not triggering

 await client.connectTCP("127.0.0.1", { port: 502, keepAlive:true }).catch(console.log); // only the catch throw
`

Is it because of https://github.com/yaacov/node-modbus-serial/blob/master/ports/tcpport.js#L152 ? the error is not emited to the ModbusRTU.
