Xinje XL Series - 6-5 Read write serial port parameters; 6-5-1 Read serial port parameters [CFGCR]

296
6-5 Read write serial port parameters
In addition to modifying communication parameters through serial configuration panel, it can
also be realized by reading instruction [CFGCR] of serial parameters and writing instruction
[CFGCW] of serial parameters.
