Hi Emmanuel,
One of the arguments passed to the asynPortDriver constructor is a bit-mask of all of the asyn interfaces your driver will support.
You forgot to set the asynOctetMask bit in your call to the constructor. Here is an example from asyn/testErrorsApp/src/testErrors.cpp
testErrors::testErrors(const char *portName)
: asynPortDriver(portName,
1, /* maxAddr */
(int)NUM_PARAMS,
/* Interface mask */
asynInt32Mask | asynFloat64Mask | asynUInt32DigitalMask | asynOctetMask |
asynInt8ArrayMask | asynInt16ArrayMask | asynInt32ArrayMask | asynFloat32ArrayMask | asynFloat64ArrayMask |
asynOptionMask | asynEnumMask | asynDrvUserMask,
/* Interrupt mask */
asynInt32Mask | asynFloat64Mask | asynUInt32DigitalMask | asynOctetMask |
asynInt8ArrayMask | asynInt16ArrayMask | asynInt32ArrayMask | asynFloat32ArrayMask | asynFloat64ArrayMask |
asynEnumMask,
0, /* asynFlags. This driver does not block and it is not multi-device, so flag is 0 */
1, /* Autoconnect */
0, /* Default priority */
0) /* Default stack size*/

Subject: setStringParam in my asynPortDriver
I am moving one of my soft devices (a watch with multiple chronometers, time stamps, etc)
to asyn. I converted my "Current_time" record's from TimeStamp to stringin with asynOctetRead DTYP.
In the asynPortDriver thread, I do
setStringParam(P_CurrentTime, "<time_string>")
But when I start the IOC, that line cause the following error:
WATCH:8:CrntTimeSI devAsynOctet::initCommon interface asynOctet not found
which apparently means that the asynOctet interface is not registered.
Isn't the asynPortDriver supposed to take care of that?
I looked at the areaDetector code (where setStringParam is frequently used) to no avail.
What am I doing wrong?
Regards,
