Can't initialize port settings

Recommended Posts

I'm using my ctl file with a new PC running Windows 10 IoT Enterprise.  I am having trouble getting DAQFactory to recognize my COM ports.  The new PC is able to successfully initialize the COM ports and read from multiple slaves using Modscan as a test, but when I try in DAQFactory, I get the error message:  "Unable to initialize Com1: Can't set port settings".

That is most likely due to the flow control settings not being supported by your specific comm port.  That particular error message occurs when DAQFactory asks Windows to configure the baud, byte size, parity, stop bits and flow control settings of your port.  The other possibility would of course be an unsupported baud, byte, parity or stop bits, with baud being the most likely of those 4.
