Problems with StreamDevice

[Mark Rivers via Tech-talk <tech-talk@aps.anl.gov>]

I am running StreamDevice 2.8.8.  I am having 3 issues.  I don’t know if these are bugs or features, because I cannot find the release notes for StreamDevice.  Where are they located?

 

1)      StreamDevice seems to set asynTraceMask to 0 for the port.

 

This is my startup script.

asynOctetSetInputEos(PORT, 0, "\r\n")

asynOctetSetOutputEos(PORT, 0, "\r")

asynSetTraceIOMask(PORT, 0, 2)

asynSetTraceMask(PORT, 0, 9)

asynSetOption(PORT, 0, "disconnectOnReadTimeout", "Y")

 

dbLoadRecords("stream2.db", "P=13TEST:, R=R:, PORT=PORT")

dbLoadRecords("$(ASYN)/db/asynRecord.db", "P=13TEST:, R=asyn1, PORT=PORT, ADDR=0, IMAX=80, OMAX=80")

 

iocInit

**************************

 

Note that it sets the trace mask to 9 with asynSetTraceMask.  However, when I boot and look at the trace mask with asynReport it is 0.  The TraceIOMask is 2 like I set it, but the traceMask is 0.

If I uncomment the line that loads the StreamDevice records then asynTrace is set correctly when I boot.

If I put the asynSetTraceMask after iocInit it works.  Is this indeed something StreamDevice is doing?

 

2)      If I have an error in my protocol file I am not seeing any error messages.  I used to see them in previous versions.

 

This is what the protocol should be, command is CHN.

 

readChans {

   out "CHN:?";

   in "CHN:%d";

}

 

If I break the protocol by changing CHN to CHAN

readChans {

   out "CHAN:?";

   in "CHAN:%d";

}

 

then this is what I see with asynTrace on.  Note that the CHAN:? command returned NAK:00 which the protocol won’t parse.

The record is indeed in invalid alarm but I don’t see any error messages from StreamDevice (STAT=CALC, SEVR=INVALID).  Is this new behavior to see no errors?

3)      If I have a communications error I don’t see any error messages.  I used to see them in previous versions.  This is what I see when I disconnect the cable to my device.

There are no error messages from StreamDevice.  This is with disconnectOnReadTimeout=Y, but there are no messages with that not set either.

 

Thanks,

Mark
