Subject: asynDriver problem with vxi11

Hi all,

I got an error message from asynDriver in vxi11Configure:

vxi11Configure("TWAL",     "172.20.2.89",           1,    0.0,"gpib0")

A call to 'assert(pgpibPvt)'
    by thread 'TWALSRQ' failed in ../asynGpib/asynGpib.c line 633.
EPICS Release EPICS R3.14.12.2 $Date: 2011/12/14 08:56:55 $.
Local time is 2012-03-21 10:00:02.078465710 CET

By looking into the code I found that the SRQ handler is called but pgpibPvt, which is taken from pasynUser->userPvt, is not set. I guess this may happen when a SRQ is already active when the port is configured and autoconnect is active.

I am using asyn 4-16.

Dirk
