I know why it is happening.  Ana is doing this before iocInit.

asynSetTraceMask("L0", -1, 0xFF)

The problem is that using the address of -1 on asynSetTraceMask set the trace mask of all device address that are currently connected to that asyn port.  However, at that point the GPIB device at address 19 has not yet been connected, so its asynTraceMask does not get set.

The solution is to move that line to after iocInit.  You won’t see any trace information that should happen as part of iocInit, but you will see everything after that command is issued.

We might want to change the way asynSetTraceMask($(PORT), -1, MASK) works to avoid this confusion.  Someone else ran into this a couple of weeks ago.
