6.4.4.4 Stop bit (AT+C1_STOPB)
Command format
AT+C1_STOPB=<stopb>\r\n
AT+C1_STOPB?\r\n
Return value
6.4.4.5 Parity bit (AT+C1_PARITY)
Command format
AT+C1_PARITY=<parity>\r\n
AT+C1_PARITY?\r\n
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.
