&Z command: Store phone number
The AT&Z command stores “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. You can
store one telephone number for each ASY port. For example, to store the phone number 0800
123456 as the default number to be associated with ASY 2, enter:
at&z2=0800123456
If the number of the ASY port is not specified, the number is stored according to the port from which
the command was entered. For example, entering this command from ASY 3:
at&z=0800123456
Has the same effect as this command being entered from any port:
at&z3=0800123456
Once a number is stored, you can dial it from the command line using the ATD command with the
S= modifier:
atds=3
This means that you can dial any stored number from any port. If DTR dialing has been is enabled by
setting S33=1 for the port, the number associated with that port is dialed when the DTR signal for
that port changes from Off to On. This is because you can use DTR dialing with the number
associated with the port to which the terminal is connected only.
\AT command: Ignore invalid AT commands
This command is a work-around for use with terminals that generate large amounts of extraneous
text. If not ignored, this text can cause many error messages to be generated by the router, and may
result in a communications failure. To turn on this feature, type the following command:
at\at=1
To turn off the feature, type the following command:
at\at=0
When this feature is turned on, the ASY port ignores all commands except real AT commands. As
with other ASY modes this can be saved by AT&W but is not included in the AT&V status display. To
determine whether or not this mode is enabled type:
at\at ?
The router will display 0 if the feature is Off, 1 if it is On.
\LS command: Lock speed
The AT\LS command locks the speed and data format of the port at which it is entered to the
current settings so you can use non-AT application commands.
