Notes
• Following settings are supported:
- 7 bits, even parity, 1 stop bit (
- 7 bits, odd parity, 1 stop bit (
- 8 bits, even parity, 1 stop bit (
- 8 bits, no parity, 1 stop bit (
- 8 bits, odd parity, 1 stop bit (
- 8 bits, no parity, 2 stop bits (
• If 7E1 and 7O1 mode are set with
remote party requires the parity bit to be transmitted, additional settings must be made via
• 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.
• TC35i's autobaud feature detects the bit rate currently used by the TE. However, this detection suffers some
limitations described in chapter 4.10.1. If autobauding is enabled, the
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
• 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>
=2), you need to explixitly set the parameter
<format>
'+CME ERROR: invalid index'. This is because for
nal value 'no parity' which is not supported by
ted for which no default is stated in this specification, the value of the parameter remains unchanged).
