The devGpib layer is set up for command/response devices.

Your original messages says that your device sends unsolicited

messages. This requires a different type of driver. The streamDevice

package provides a nice mechanism for handling devices that send

unsolicited messages.

The report(asynReport 10,“L16”) is as follows:

synchronouslock=NO when working properly

ynchronouslock=YES when not working. other things are as it is

except readcount(character)

how can I fix it?

When it stops working, what do you see?

Here are some things to try:

- When it stops working, issue the following command:

asynReport 10,“L16”

This asks for a detailed report on the state of that asyn port.

Next, issue the following commands:

asynSetTraceIOMask “L16”,0,2

That enables TraceEscape output, printing ASCII plus escape sequences.

asynSetTraceMask “L16”,0,255

That turns on all trace output for your asyn port on address 0. If

you are using other addresses you might need to issue commands like:

asynSetTraceMask “L16”,2,255

for address 2, etc.

This should tell you if you are getting disconnected from the

terminal server (TCP/IP disconnect) or if the device is sending

garbage, etc.

I am using ‘asyn’ to communicate with a custom made device using

‘HowTodoSerial’ concept where CommonGpib functions are used.

The device continuously sends data if a knob, attached to it,

rotates and does not send anything otherwise.

The IOC is working properly as long as the knob rotates but stops

working after some time when there is a long gap.The device is

connected through a Serial to Ethernet Converter by

drvAsynIPPortConfigure("L16","192.168.0.10:10003",0,0,0)

 in st.cmd file.

TIME_WINDOW=1000

Asyn version=4-4

Base= base-14.8.2

Is it a time out problem? Is it disconnecting from device after

timeout?

Additionally I also want to know how can I flush a particular serial

buffer in this program?Is flushbuffer function is available here?
