Dear all,
testAsynPortDriver is a pretty good example for learning basic usage of asynPortDriver, however I encountered a warning message that I do not understand when made some modifications and ran it.
The initial status of the digital scope simulator is "Stop", if I try to set the initial status to "Run" by changing Line 102 of https://github.com/epics-modules/asyn/blob/master/testAsynPortDriverApp/src/testAsynPortDriver.cpp
from
setIntegerParam(P_Run, 0);
to
setIntegerParam(P_Run, 1);
then make and add "asynSetTraceMask("testAPD", 0, 0x20)" to the end of st.cmd, the following warning will display continuously,

In order to install the old MEDM, the test environment is old as follows,
Debian 7 wheezy
base-3.14.12.5
asyn-R4-44-2
Any hint or suggestion is appreciated.
Thanks,
Lin
