Hi Dirk,
Unfortunately this does not solve my problem. I am using epics
R3.14.9 and asyn 4-9. This is the output I get with my simple test
soft IOC:

Are you using earlier versions of Epics or asyn? If you are using
the same version of these two packages, am I missing something in my
Makefile or some other files?
Thanks for helping,

Hello Zen,
I tested @init handlers with several devices today. I found that TCP
ports as well as serial ports work as expected. The problem only
occurs with vxi11 ports.
However, I got different error messages:
--------------------------------------------------------------
2007/11/05 13:57:32.057 gpib0,8 vxiCreateDeviceLink RPC error
: RPC: Timed out
2007/11/05 13:57:32.058 L0 vxiCreateDevLink failed for addr 8
2007/11/05 13:57:32.058 asynManager::asynConnectCallback, port L0
error calling

2007/11/05 13:57:36.067 L0 vxi11 clientCall errno 0 clnt_stat
5 L0 vxiBusStatus RPC error : RPC: Timed out
2007/11/05 13:57:36.067 L0 asynGpib:srqPoll srqStatus error timeout
2007/11/05 13:57:40.077 L0 vxi11 clientIoCall errno 0 clnt_stat 5
2007/11/05 13:57:40.077 DZ:cmd: asynError in write: L0 RPC failed
2007/11/05 13:57:40.078 DZ:cmd: @init handler failed
2007/11/05 13:57:40.078 DZ:cmd: Record initialization failed
----------------------------------------------------------------
StreamDevice error messages start with "asynError in write:
L0 RPC failed". All above is drvVxi11 or asynManager.
I tried to do some debugging with the asynTrace facility and found
that the problem disappears as soon as I call asynSetTraceMask, even
with a 0 mask!
Thus try this in your startup script:
...
vxi11Configure( "L0","134.79.64.25",0,0.0,"gpib0",0,0)
asynSetTraceMask ("L0",8,0)
...
However, I still have not the slightest idea what goes wrong in the
vxi11 driver.
I Hope this helps.
Dirk
