3.5.2.2.5. Fixed DTE Interface Rate - +IPR
+IPR - Fixed DTE Interface Rate
AT+IPR=<rate>
Set command specifies the DTE speed (UART only) at which the device accepts
commands during command mode operations; it may be used to fix the DTE-DCE
interface speed.
Parameter:
<rate>
19200
38400

115200 (default)
230400
460800
500000
750000
921600
1843200
3000000
3250000

AT+IPR?
Read command returns the current value of +IPR parameter.
AT+IPR=?
Test command returns the list of fixed-only <rate> values in the format:
+IPR: (list of fixed-only <rate> values)
Reference V25ter
3.5.2.2.6. DTE-Modem Character Framing - +ICF
+ICF - DTE-Modem Character Framing
AT+ICF=<format>
[,<parity>]
Set command defines the asynchronous character framing to be used when
autobauding is disabled.
The HE863 family supoports only the 8 Data, 1 Stop setting.
Parameters:
<format> - determines the number of bits in the data bits, the presence of a parity
bit, and the number of stop bits in the start-stop frame.
3 - 8 Data, 1 Stop (default)
<parity> - determines how the parity bit is generated and checked, if present;
setting this subparameter has no meaning.
0 - Odd (not supported)
1 - Even (not supported)
AT+ICF?
Read command returns current settings for subparameters <format> and <parity>.
The current setting of subparameter <parity> will always represented as 0.
AT+ICF=?
Test command returns the ranges of values for the parameter <format>.
