dynamic library RF60x.dll
file for static linking of DLL to project RF60x.lib,
Definition file RF60x.h.
The SDK allows user to develop his / her own software applications without going
into details of the sensor communications protocol.

Connection to COM-port (RF60x_OpenPort)
The function RF60x_OpenPort opens COM-port with specified symbolic name,
fills in the pointer to the device descriptor and returns the operation result.
Parameters:
lpPort_Name
–
name of COM-port (e.g., “COM1:”), full syntax for COM-
port name specification see in MSDN, function CreateFile;
dwSpeed
-
operation speed through COM-port. The
parameter is identical to field BaudRate in DCB structure described in MSDN;
lpHandle
-
pointer to the device descriptor;
Returned value:
If COM-port fails to be opened and adjusted, the function will return FALSE,
otherwise if COM-port was opened and adjusted successfully the function will
return TRUE. More detailed information about returned errors can be obtained
