Hello,
I am running two different instances from 2 different folders.
On instance 1 I want to switch DTR
On instance 2 I want to swtich RTS
But once 1 pin is switched (DTR or RTS), it is impossible to switch the other.
Can you help please
-
There's no solution, only one application can access the serial port in Windows.
-
What does happen if I create a second Com port using USB to serail converter ?
-
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.

TKS.
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.
This equipement works nicely for other pruposes.
