AT+C1_DATAB=<datab>\r\n

<datab>

0: 7 bit

1: 8 bit (default)

Define new value

AT+C1_DATAB?\r\n

Query current value

Return value

[C1_DATAB] Value is: <datab>\r\n

6.4.4.4

Stop bit (

AT+C1_STOPB

)

Command format

Parameters

Usage

AT+C1_STOPB=<stopb>\r\n

<stopb>

0: 0.5 bit

1: 1 bit (default)

2: 1.5 bit

3: 2 bit

Define new value

AT+C1_STOPB?\r\n

Query current value

Return value

[C1_STOPB] Value is: <stopb>\r\n

6.4.4.5

Parity bit (

AT+C1_PARITY

)

Command format

Function value

AT+C1_PARITY=<parity>\r\n

0: none (default)

1: Odd

2: Even

Define new value

AT+C1_PARITY?\r\n

Query current value

Return value

[C1_PARITY] Value is: <parity>\r\n

6.4.4.6

Serial flow control (

AT+C1_SER_C

)

Command format

Parameters

Usage

AT+C1_SER_C=<c>\r\n

<c>

0: None (default)

1: Hardware flow control

Define new value

AT+C1_SER_C?\r\n

Query current value

Return value

[C1_SER_C] Value is: <c>\r\n

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
