Using Commands
To execute a command, send the command name and any parameters separated by spaces, followed by
a line ending. For example, to use the ATDT command to set the destination address to 1234, send:
ATDT 1234<LF>
Some commands may output result information on lines following the command, but the output will
always terminate with either the OK sequence (introduced in the previous section) or the ERROR
sequence (ERROR<CR><LF>).
Some commands may have different results depending on the number of parameters. In general, a
command that sets a parameter(s) can read back its values by issuing the command with no parameters.
To get on-line help with a command, enter the command with a question mark at the end.
To see a list of all commands, use the HELP command.

– Sets serial com port baud rate (bps). Over-the-
air (throughput) baud rate is set with ATR2 command.
