1.2.1. Combining AT Commands on the Same Command Line

You can enter several AT Commands on the same line. In this case, you do not need to type the "AT" or
"at" prefix before every command. Instead, you only need type "AT" or "at" at the beginning of the
command line. Please note that use a semicolon as command delimiter.
The command line buffer can accept a maximum of 256 characters. If the input characters exceeded the
maximum then no command will be executed and TA will return "ERROR".

1.2.2. Entering Successive AT Commands on Separate Lines

When you need to enter a series of AT Commands on separate lines, please note that you need to wait
the final response (for example OK, CME error, CMS error) of the last AT command you entered before
you enter the next AT command.
