Printer Sharing
On the ida 812-1x MIO it is possible to use parallel output from an
IBM PC, as the printer interface contains a printer sharing module.
For both the twinax port and the parallel port, you can program a
user string to be used for initialisation in a share situation. This
string is defined via FSL Function 100 "Port Sharing Option", where
a timeout is specified (See Chapter 7. and Appendix A. for further
details on FSL functions).1
The printer sharing module may be in one of two states:
•Twinax session mode
•Parallel session mode
When none of the modes are active, the twinax line will answer
READY and the twinax and parallel lines are polled in turn.
If data is sent on the parallel line, the module will enter Parallel
Session mode. The twinax line will answer that the unit is HOLD.
1Y100 for the parallel port is defined via Y246 (See Chapter 7. for further details).
