Hello,

 

I am trying to understand how to setup a particular command in a protocol file.

 

The command looks like this:

 

Battery On “number”

 

And the command returns either: “OK” or ”Error: err msg”.

 

 

I think my protocol file might look like this:

 

Battery

{

 Out “Battery On %d”;

}

 

And my db file would look like this:

 

Record (longin, “batteryOn”)

{

  Field(DTYP, “stream”)

  Field(INP, “myDev.proto Battery dev”)

}

 

 

How do I get the status that the command returns?

 

I want to do something like

 

Battery

{

  Out “Battery On %d”;

  In “%s”;

}

 

 

But I am already using an input for the battery number.  So how do I do both?

 

Thanks In advance.
