US Robotics COURIER - Modem Redialing Options

COURIER HIGH SPEED MODEMS
Dial the Last Dialed Number (DL)
When sent this command, the modem dials the last dialed
number, which it has stored in a special buffer:
ATDL
To display the number stored in the last-dialed buffer, use the
following command:
ATDL?
To write the last number dialed to NVRAM, use &Zn= L where
n is the position in NVRAM. The following example stores the
last dialed number at position 3:
&Z3 = L
If a number is already stored at position 3, that number is over-
written with the last-dialed number.
Re-execute the Last Command (A/,)
The A/ command, which does not take the AT prefix or a Car-
riage Return, redials one time:
A/
When the modem receives a command, it stores the instruction
in its command buffer until it receives the next AT command.
Note that if you've sent the modem an additional command
since the Dial command, A/ re-executes that command instead
of redialing.
Automated Redialing(>, A>)
These two commands, while they can be used to continuously
repeat any command, are designed for automated redialing. The
first (>) is included in the Dial command. The second (A>) is
used alone to continuously redial the command string in the
buffer.
