 I tried with a cheap converter and as you said, it does not mange DTS, RTS.
To avoid problems to other users , product is from newlink products.

If there are more COM ports in the system, each can be accessed by one instance. However note that some low-cost USB to RS232 converters do not implement DTR/RTS control.

There's no solution, only one application can access the serial port in Windows.
