Ask for advice on how to use the 232 serial port for data communication under DOS. How should it be set in CONFIG.SYS? Please have experts reply on the settings. Is it using the MODE command? It is best to give a complete reply on the serial port definition, baud rate, parity check, etc. That is, the complete reply of MODE. If there is no parity check, is parity check = 0 selected? Thanks in advance.

No need to set in CONFIG.SYS, just use the MODE command. MODE COMm[:] [BAUD=b] [PARITY=p] [DATA=d] [STOP=s] [RETRY=r] COMm m is the serial port number BAUD=b baud rate PARITY=p odd/even parity DATA=d data bits STOP=s stop bits RETRY=r retry count For details, see: mode /? or help mode for detailed introduction
