Datasheet

42 7. Command Overview
AT&S<n> Sets function type of the control line DSR
<n> 0 DSR always on
1 Device in command mode: DSR off
2 Device in data mode: DSR on
AT&V Displays current configuration
AT&W Store current configuration
AT\Q<n> Data flow control of the serial interface
<n> 0 Off
1 Software handshake (XON/XOFF)
2 Only CTS
3 Hardware handshake (RTS/CTS)
ATTENTION: In hardware handshake mode, the INSYS GSM small can still supply
up to 264 data bytes (worst case) after the application has deactivated the RTS
signal.
AT+ICF? Query the data format of the RS232
If auto bauding (AT+IPR=0) is active, the currently detected data format is not
displayed, but the data format which was used for deactivated auto baud.
AT+ICF=<format>
[,<parity>]
Data format of the RS232
<format> 1 8 data bits, 0 parity bits, 2 stop bits
2 8 data bits, 1 parity bits, 1 stop bit
3 8 data bits, 0 parity bits, 1 stop bit
4 7 data bits, 1 parity bits, 1 stop bit
<parity> 0 Odd parity
1 Even parity
The parameter <parity> must only be specified, when a parity bit is specified
in the parameter <format>.
The following settings are supported:
7E1 (AT+ICF=5,1)
7O1 (AT+ICF=5,0)
8E1 (AT+ICF=2,1)
8N1 (AT+ICF=3)
8O1 (AT+ICF=2,0)
8N2 (AT+ICF=1)
For the settings 7E1 and 701, the parity is per default not forwarded to the
remote terminal. If this is necessary, an additional setting must be performed
