Subject: Re: stream without asynPort From: Dirk Zimoch <[email protected]> To: [email protected] Date: Mon, 21 Feb 2011 10:02:31 +0100 Hi Emmanual,By design, a StreamDevice record needs to connect to a "bus". At the moment, I only support asynDriver as a bus system. For your application, you don't need it. Thus a "dummy" bus driver would do. I already have a "debug" bus driver that simply prints what function is called. From this is should be easy to write a "dummy" driver. I will try.Dirk [email protected] wrote:Hello, I am tryign to use a feature I have seen in stream protocols. I would like to call iocsh function from a process variable.ex: when a bo record is set to 1, I would like to execute 'dbl' in the iocsh.Q: is it possible to use stream without instanciating a asynPort ? Q: is there another SIMPLE way to do this other than with stream ? Q: apropos is it possible in stream to pass the value of the PV in exec lines? ex: exec "dbpr mbboPV <valueOfMbboPV>" ; Thanks,
