Local Character Framing [AT+icf]
This parameter determines the local serial port asynchronous data framing. The second parameter is needed only if you
select fewer than eight data bits.
Command &ICF
Action
AT+icf=
Query
AT+icf?
Range
AT+icf?
Framing
Parameter
Values:
0 = AutoDetect
3 = 8 data bits, 1 stop bit
5 = 7 data bits, 1 parity bit, 1 stop bit

Values:
0 = Odd
1 = Even
2 = Mark
3 = Space
Local Flow Control (PCCA) [AT+ifc]
This extended compound parameter controls, the local flow control between the computer and the modem. The two numeric
sub-parameters are DCE_by_ DTE (which controls the data format he modem) and DTE_by_DCE (which controls the data
from the computer).
NOTE: To change the setting of these parameters, use the &K command.
Command +IFC
Action
AT+ifc= <DCE_by_DTE>, <DTE_by_DCE>
Query
AT+ifc?
Range
AT+ifc=?
DCE_by_DTE
Parameter
Values:
0 = No flow control was set by DTE.
1 = XON/XOFF; do not pass XON/XOFF characters
to the remote DCE.
2 = RFR active/inactive flow control
3 = XON/XOFF; Pass DC1/DC3 characters to the
remote DCE in addition to acting upon local flow
control.
DTE_by_DCE
Parameter
Values:
0 = No flow control was set by DTE.
1 = XON/XOFF flow control
2 = CTS/RFS active/inactive flow control
