1, check the original map folder NaviOne (mostly with this name), with a txt file of SUPCFG, or with the name config, etc. As long as there is a similar txt file, and the original picture can be searched for stars, open this file with notepad, which contains:

(The file SUPCFG.txt in NaviOne folder of Khalid map in HD version, the port shown above is COM2, and the baud rate is 9600).

2. If there is no SUPCFG.txt file mentioned above in the original Khalid diagram, there is a NaviConfig.dll file in the NaviOne/NaviResFile directory, which can be read and modified by the Khalid profile parsing and reference tool (Khalid port rate modifier tutorial).

3. If both files are available, the SUPCFG.txt file has the highest port rate permission, and there is no need to modify the NaviConfig.dll file.
