7.1.1. User String as Input

Function Y90, User Escape String Definition is used to define a
string which can be sent to the interface as input. Since the string is
sent as input to the interface it can be used to change FSL setup
functions.
In Function 90, you may define strings with "identifiers" in HEX de-
pending on the available memory area in the permanent memory
area. These strings are sent as input to the interface when escape
"identifier" is received via the line.
