Query string command types and syntax
As with SSI formatted commands, query strings can use any valid SIS command of either
type (host or remote).
• Host commands instruct the IPL T SFI244, itself, to act or respond.
• Remote commands send data to an external control port on the IPL T SFI244.
The basic format for a query string with a link is as follows:
x”>linked text where x is the SIS command
to be executed.
">
Delimiter Delimiter
