Xinje XD5 - Read Write Serial Port Parameters; Read Serial Port Parameters [CFGCR]

271
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.
