· If <format>2, the parity bit will not be transported on the radio path.
· When using a bit rate of 300 bps there must be a delay of 500ms before
entering the next command. At bit rates of 1200 bps the delay must be
300ms. For higher rates a delay of 100ms is sufficient.
· The autobauding feature (see Chapter 2.47 ) also detects the character
framing. If autobauding is enabled, the AT+ICF Read command does not
show the active character framing, but the character framing that will be
used when the autobauding is disabled.
· For compatibility reasons, the command can be used in Multiplex mode,
though the settings will not take effect. Please note that changes made on
multiplex channel 1 will be saved with AT&W and will become active when
restarting the ME after AT^SMSO.
· To restart the multiplexer it is necessary to set the character framing to
8 bits, no parity and 1 stop bit.
· If a <format> is selected without parity (“no parity”), e.g. <format>=3, and
you try to activate a format with <parity>, e.g. <format>=2, the parameter
<parity> must be explicitly stated, e.g. ICF=2,1. Otherwise you will get
'+CME ERROR: invalid index'. This is because for <format>=3, the pa-
rameter <parity> is set to the internal value “no parity” which is not sup-
ported by <format>=2.
Remember that if an optional parameter is omitted for which no default is
stated in this specification, the value of this parameter remains unchanged.
