Experimental Physics and Industrial Control System

I wrote a simply asynOctet driver to do this. I've not yet packaged this up for official release until I hear back from the folks testing this. I'm not 100% sure that it's a good idea to allow commands to be run as the result of record processing, but maybe there's a real need out there. On Feb 21, 2011, at 1:03 AM, Dirk Zimoch wrote:

Subject: Re: stream without asynPort
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.

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,
