> 1.4.2 | Combining AT commands on the same command line

> You may enter several AT commands on the same line. This eliminates the need to type the "AT" or "at" prefix before each command. Instead, itis only needed once at the beginning of the command line. Use a semicolon as command delimiter.
> The table below lists the AT commands you cannot enter together with other commands on the same line. Otherwise, the responses may not be in the expected order.

> AT command type | Comment
> V.250 commands | with FAX commands (Prefix AT+F)
> GSM 7.07 commands | with Siemens commands, Prefix AT^S)
> GSM 7.05 commands (SMS) | To be used standalone
> Commands starting with AT& | To be used standalone
> AT+IPR | To be used standalone

> Note: When concatenating AT commands please keep in mind that the sequence of processing may be different from the sequential order of command input. Therefore, if the consecutive order of the issued commands and the associated responses is your concern, avoid concatenating commands on the same line.
