153	BNC is unable to open serial port	mike	stuerze	"I am using BNC v2.12.18 under Windows 10 64-bit.  I have configured it to receive an NTRIP stream containing RTCM3 messages from a local caster, and this appears to be working.  I now wish to configure BNC to forward the RTCM3 messages to a serial-connected GNSS receiver.

The GNSS receiver is an embedded module (mini-PCIe form factor) which appears in Windows as a virtual serial port (COM49).  I have entered the mountpoint, port name and baud rate on the Serial Output tab, but BNC is consistently unable to open the port.

I have confirmed that the baud rate is correct and that the port exists in Device Manager.

I have confirmed that no other application has opened a connection to the port.

I have attached my BNC config file (with my credentials removed), a log file, and two screenshots.

What am I doing wrong?"	defect	closed	normal	BNC		fixed
