Xerox FS 5250 IPC 用户手册

In order to ease customisation of the Xerox FS 5250, FSL parame ters for
twinax input can be programmed directly via the interface's Centronics or
serial (RS-232) port using the Engineering Function Y249.

The Engineering Function enables the system to detect whether FSL
sequences on shareport are intended for twinax FSL input or for shareport
setup and will direct the sequences received to the twinax FSL interpreter.

The sequence works as a switch for FSL sequences. The defined Escape
Character will also be translated and defined as Escape Character for the
twinax FSL module. The ability to set up via the shareport is reset after
timeout on the shareport and can not be saved in the NVRAM

.

The setup sequence must only contain ASCII characters.  Apostrophe
notation can be used if characters are included in the US ASCII 7 bit
character set, all other data must be in HEX notation.

All functions which are accessible from the twinax input can be used via
Centronics/RS-232 setup.

Before the Engineering Function can be activated, an Escape character
must be defined:
