Does anyone have an assembler example to "ring the bell" on a 3270 terminal?

Umm CALL ISPLINK,(DISPLAY,DING),VL where the panel code contains .ALARM = YES.

Clearly not helpful ?

In more detail go find the 3270 data stream reference manual and look up the MDT bits. It seems to be very hard to find this book these days : GA23-0059

Clearly I've forgotten what the MDT bits were for :-)

Does IBM still label bits from the MSB? Is bit zero in the diagram the MSB?
