|
|
<P>
|
|
dip only understands a predefined set of variables. A
|
|
variable name always begins with a dollar symbol and must be
|
|
written in lower-case letters.
|
|
<P>
|
|
The $local and $locip variables contain
|
|
the local host's name and IP-address. Setting the hostname makes
|
|
dip store the canonical hostname in $local,
|
|
at the same time assigning $locip the corresponding
|
|
IP-address. The analogous thing happens when setting the
|
|
$locip.
|
|
<P>
|
|
The $remote and $rmtip variables do the same for
|
|
the remote host's name and address. $mtu contains the MTU
|
|
value for the connection.
|
|
<P>
|
|
These five variables are the only ones that may be assigned values
|
|
directly using the get command. A host of other variables can
|
|
only be set through corresponding commands, but may be used
|
|
print statements; these are $modem, $port,
|
|
and $speed.
|
|
<P>
|
|
$errlvl is the variable through which you can access the
|
|
result of the last command executed. An error level of 0 indicates
|
|
success, while a non-zero value denotes an error.
