&Z command: Store phone number
The AT&Z command is used to store “default” telephone numbers within the router that may
subsequently dialed when DTR dialing is enabled or by using the S= modifier in the ATD dial
command. One telephone number may be stored for each ASY port. For example, to store the
phone number 0800 123456 as the default number to be associated with ASY 2, use the
command:
at&z2=0800123456
If the number of the ASY port is not specified, the number will be stored against the port from
which the command was entered, such as entering the command:
at&z=0800123456
from ASY 3 has the same effect as:
at&z3=0800123456
from any port. Once a number has been stored it may be dialed from the command line using the
ATD command with the S= modifier:
atds=3
This means that any stored number can be dialed from any port. If DTR dialing has been enabled
by setting S33=1 for the port, the number associated with that port will be dialed when the DTR
signal for that port changes from Off to On, such as DTR dialing can only be used with the
number associated with the port to which the terminal is connected.
