MODEM 325 AND MODEM 325 CARD
6.4.7 R C
EPEATING A OMMAND
This command tells the modem to repeat the last command stored in its buffer. It automatically
reexecutes the command without retyping. The return key does not need to be pressed.
Example: The ATD5551212 command has been executed, and the phone is busy. To repeat the
instruction type A/, but do not use AT before this command, since AT would empty the buffer and there
would be no command to repeat.
6.4.8 N C
UMBERED OMMANDS
Series of commands that start with the same letter are distinguished by a number called a command
parameter following the letter.
For example, the M0 command selects speaker always off, M1 speaker on until carrier detected, and
M2 selects speaker always on.
In all cases, the zero (0) may be omitted. So the commands M and M0 are identical.
This manual uses the commands without the zero. The modem treats both the same but zeros count
against the buffer total.
6.4.9 G C
ROUP OMMANDS
A group of commands can be typed in a single command statement. Pressing the return key sends the
entire command string to the modem, which executes each command individually in the order in which
it appears in the command statement.
For example, the command statement ATQ0V0L3DT5551212 means
AT Attention.
Q0 Allow response messages to be sent.
V0 Select digit code responses.
L3 Select high volume.
DT Tone-dial 555-1212.
The modem executes the AT command followed by the Q, V, L, D, and T commands. Command
statement ATQ0V0L3DT5551212 can be read: ATQVL3DT5551212. Eliminating zeros reduces the
number of characters in a command statement, thereby simplifying typing and allowing more room in
the buffer.
The dial D command initiates the dial process, so no other commands, only dial modifiers, can follow
the D command.
