TC63 AT Command Set
4.6 AT+ICF
Notes
•
If
modes 7E1 or 7O1 are set, the parity bit will by default not be transmitted over the air. If the remote
AT+ICF
party expects the parity bit to be transmitted, additional settings are required via AT^STPB.
•
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 bit rates use of the default delay is sufficient.
•
TC63's autobaud feature detects the bit rate currently used by the TE. However, this detection suffers some
limitations described in Section 4.9.1, Autobauding. If autobauding is enabled, the
does not show the current character framing, but the character framing that will be used when 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
when restarting the ME after AT^SMSO.
•
To start the multiplexer it is necessary to set the character framing to 8 bits, no parity and 1 stop bit.
•
If a
is selected without parity (e.g. <format>=3) and you try to activate a format with parity (e.g.
<format>
<format>=2), you need to explixitly set the parameter
'+CME ERROR: invalid index'. This is because for <format>=3, the parameter
nal value 'no parity' which is not supported by <format>=2. (Remember that if an optional parameter is omit-
ted for which no default is stated in this specification, the value of the parameter remains unchanged).
