Return value
6.4.4.6 Serial flow control (AT+C1_SER_C)
Command format
AT+C1_SER_C=<c>\r\n
AT+C1_SER_C?\r\n
Return value
This command activates the hardware flow control. This could improve the data accuracy for high speed
transmission. Note: If turn on this function, the counter serial device also need to turn on this function.
6.4.4.7 Clear serial buffer if connect (AT+C1_BUF_CLS)
Command format
AT+C1_BUF_CLS=<class>\r\n
AT+C1_BUF_CLS?\r\n
Return value
If there is disconnection during data communication, serial buffer may still contain data which haven't send out.
This command could handle usage of those remaining data in serial interface after reconnection.
6.4.4.8 Data packaging size (AT+C1_SER_LEN)
Command format
AT+C1_SER_LEN=<len>\r\n
AT+C1_SER_LEN?\r\n
Return Value
When receiving data from serial port, this value defined the length of single data package each time.
6.4.4.9 Data packaging time (AT+C1_SER_T)
Command format
AT+C1_SER_T=<time>\r\n
AT+C1_SER_T?\r\n
Return value
When receiving data from serial port, this value defined the time frame for sending the data in buffer.
