Linux recognises the USB port of the AETA as a modem, thereby fitting in the Abstract Control Model (ACM) sub-class. This can be implemented in the default RedHat 7.1 and 7.2 installations. The default installation doesn't produce the device nodes. The device nodes can be generated using the INST_USB.SH script in the Linux Utils directory. This script generates 4 device nodes in /dev/usb/, they are ttyACM0 - 4. Usually the node to use will be ttyACM0
To confirm that Linux has seen the AETA, type "cat /proc/bus/usb/devices" at a command prompt. If the AETA has been identified correctly, it will be listed in the output amongst other information as follows:
"Manufacturer = Braintree Communications" and
"Product = Argent Enhanced Terminal Adaptor"
For further information or tools for USB under Linux please go to the Linux USB site at http://www.linux-usb.org/.
Multilink PPP is used to double the
available connection speed to the Internet, this can potentially halve the time
to download web pages and files from the Internet*. The AETA does this by
making a second call to your Internet Service Provider (ISP) so that two lines
are then available for downloading information. The AETA
will make the second call to your ISP depending upon the
amount of information you are downloading from the Internet. By default it will also disconnect the second call to allow
an incoming or outgoing phone call.
If your ISP supports Multilink PPP,
you may wish it enabled. Follow the link below for instructions on
enabling Multilink PPP.
* Download times from the Internet vary due to many factors only one of which is the speed you are connected to the internet. Other factors may include the speed of the server you are connecting to and the speed and bandwidth of any connections between your ISP and the server you are connecting to.
