E.2 Variables Commands
The RabbitLink serial console has the ability to handle SSI (Server Side Includes) variables. These
variables are stored in an xmem buffer. This means that the memory will lose the variables when
power is cycled, although the references to the variables will still exist. Remember that any HTML
file that includes SSI tags must have the file extension
.shtml
.
createv <varname> <vartype> <format> <value> [strlen]
This command creates a variable and stores it in the flash file system on the RabbitLink. The
variable can be referenced in HTML files using SSI; e.g. <!--#echo var="var1"-->).
varname The name of the variable.
vartype

int8

format
The
printf
-style format specifier (such as
