Hello,

Thank you for your reply. According to your suggestion, we followed the

steps described in the stream device documentation

(HowToDoSerial(StreamDevice)) and try to run the example, but we got an

error:

drvAsynSerialPortConfigure("L0","/dev/ttyS0",0,0,0)
asynSetOption("L0", -1, "baud", "9600")
setOption failed tcsetattr failed: Input/output error
asynSetOption("L0", -1, "bits", "8")
setOption failed tcsetattr failed: Input/output error
asynSetOption("L0", -1, "parity", "none")
setOption failed tcsetattr failed: Input/output error
asynSetOption("L0", -1, "stop", "2")
setOption failed tcsetattr failed: Input/output error
asynSetOption("L0", -1, "clocal", "Y")
setOption failed tcsetattr failed: Input/output error
asynSetOption("L0", -1, "crtscts", "Y")
setOption failed tcsetattr failed: Input/output error
asynOctetSetInputEos("L0", -1, "\n")
asynOctetSetOutputEos("L0", -1, "\n")
asynSetTraceIOMask("L0",-1,0x2)
asynSetTraceMask("L0",-1,0x9)

and also when I type dbior "stream" command in epics I get the following

output:

 Driver: stream
  StreamDevice 2.6.0 built May 13 2013 15:00:53
  registered bus interfaces:
    DebugInterface
    DummyInterface.

Can you help me to resolve this problems?

In the Tech-talk I found some notes about the last output where it is

suggested to make some changes in the CONFIG_STREAM file, but I could not

find such file in my directories. Where it is located?

Thanks in advance,
Vahe.

Agreed -- and please note that recent versions of the ASYN support module include a tutorial on using StreamDevice to communicate with a device.

Hello Vahe,

I would strongly suggest using StreamDevice [1] to interface such a device.
This approach will be much easier and faster. Writing a protocol file for your device is basically all you will have to do.
