> UDP and TCP is works well.what is "another serial connection" RS485? using another serial adaptor

Try to use a [USB to UART adaptor](https://www.digikey.es/es/products/detail/ftdi,-future-technology-devices-international-ltd/TTL-234X-3V3/6823715?utm_adgroup=Smart%20Cables&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_Product_Cable%20Assemblies&utm_term=&productid=6823715&gclid=CjwKCAjw8sCRBhA6EiwA6_IF4Sge9_2Xi71oDMaV_vUEoBB9oJii285kN0MVAtVIyUPGt6-XMjiWEhoCi3wQAvD_BwE) using the UART GPIO of the RPi instead of chaining two USB-to-RS232 adaptors.

@ilikecola could you try without virtual ports in vmware in order to check that this is not a misconfiguration on that side?

@ilikecola ok, could you provide detailed instructions so we can replicate your scenario?
