\AT 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 unit will display 0 if the feature is Off, 1 if it is On.
\LS Lock Speed
The AT\LS command is used to lock the speed and data format of the port at which it is
entered to the current settings so that the non-AT application commands may be used.
\PORT Set Active Port
Text commands which affect the settings associated with the serial ports normally operate
on the port at which they are entered, i.e. entering the AT&K command from a terminal
connected to ASY 1 will affect only the flow control settings for port 1.
The AT\PORT command is used to select a different “active” port from that at which the
commands are entered. For example, if your terminal is connected to port 0 and you need
to reconfigure the settings for port 2, you would first enter the command:
at\port=2
PORT 2
OK
Port 2 is now the active port and any AT commands or changes to S registers settings which
affect the serial ports will now be applied to port 2 only. This includes:
Commands: Z, &D, &F, &K, &V, &Y, &W
S registers: S31, S45
The AT\PORT? command will display the port to which you are connected and the active
port for command/ S register settings. For example:
at\port?
PORT 2
ASY0
OK
Here, ASY2 is the active port and ASY0 is the port at which the command was entered. If
the default port and the port to which you are connected are the same, only one entry will
be listed.
To reset the default port to the one to which you are connected use the AT\PORT command
without a parameter.
