EtherLan User Guide
(twisted pair) Ethernet then the test will detect reversed cabling on its Rx (receive)
connection and will automatically correct this fault.
If any errors (other than the reversed Rx connection mentioned above) are found then the
network will not start (i.e. you will not be able to log on to your file server). Entering the
Ehinfo
command (see page 10) will show any errors discovered by the driver software
during the self test and cable check. If the computer was started without a cable connected
or if the cable was not terminated then the problem must be corrected and the computer
reset.
You can make the card perform a self-test at any time by entering the
Ehtest
command (see
page 12). However note that Ehtest only tests the Ethernet
port
to which the EtherLan card
has configured itself (see notes on Ethernet Port Auto-configuration above) - it does not
force the card to re-initialise and test the two ports sequentially.
Command Summary
The next section of this manual details the star (*) commands provided by the Ethernet
driver (EtherH or EtherHB). These are of two types:
Configuration commands: These are used to determine the state in which the computer
will start up. The settings made with these commands are remembered when the computer
is turned off
Immediate commands: These cause something to be done straight away (e.g. a test to be
carried out). Any effect of an immediate command will be lost when the computer is turned
off or reset.
In addition, it provides details of those AUN commands which are specifically required for
the installation or testing of your
i3
EtherLan card, or which differ in some way from the
command descriptions given in the AUN Manager's Guide. However, the AUN Manager's
Guide provides the full list of AUN commands.
In the command descriptions which follow the nature of each command (whether it is a
Configuration, Immediate or AUN command) is noted on the heading line. Please note that
the AUN commands will only work if the computer has been configured to start up the
AUN software (by configuring BootNet on and rebooting the computer) as described
earlier. This means these commands will not work if the card is being used on an Acorn
network, unless the computers have also been configured to start up the AUN
software.
Certain AUN commands require a parameter giving a device or interface name, e.g. for the
interface parameter of the
I fConfig
command. For all i3 EtherLan cards the
device/interface name is
eh.
The i3 EtherLan driver module name is
EtherH,
or
EtherHB
for the Avignon bridging version.
In order to enter a * command you need to press the F12 key. This takes you to the
command line at the bottom of the screen, with a * displayed as a prompt.
Note that all RISC OS * commands are case insensitive.
