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, it is only needed once at the beginning of the command line. Use a semicolon
as command delimiter.
The command line buffer accepts a maximum of 391 characters. If this number is exceeded none of the com-
mands will be executed and TA returns ERROR.
The table below lists the AT commands you cannot enter together with other commands on the same line. Oth-
erwise, the responses may not be in the expected order.
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 is your
concern, avoid concatenating commands on the same line.
