What is the make and model of your terminal server?

You either need to set the baud and parity with a Web interface or put it in the RFC mode like Eric said and then you can use asynSetOption to set them.

Hi Hawi,

Sorry, I was not being clear.

Please disable the StreamDevice debugging.

Please add the following lines to your startup script, right after the drvAsynIPPortConfigure line:

asynTraceTraceIOMask(PORT, 0, ESCAPE)
asynSetTraceMask(PORT, 0, ERROR|DRIVER)

where you replace PORT with the name of the asyn port you created. I think it might be LS325_IP.

Then restart the IOC and send all of the output.

Subject: asyn connetion to wti

Dear All,

I am trying to connect a softIOC using asyn and StreamDevice to a wti console server, which has a serial connection to a LakeShore325.

I am able to telnet to the wti and communicate with the LakeShore. I am also able to connect the softIOC to other devices and send messages.

There seems to be some issue between asyn and the wti, which is serving a standard telnet connection.

The protocol file is:
ExtraInput = Ignore;
ReplyTimeout = 2000;
Terminator = CR LF;

getID {
out "*IDN?";
        in "%s";
@init {out "*IDN?"; in "%s";}
}

Below is a log snippet from asyn. It seems to read the following data then timeout:
<ff>?<18><ff>?


Any help would be greatly appreciated.
Thank you,
Hawi
