Hi Keenan,

I believe you were the last person to work on the iocsh scripting code
in Base, could you check whether your changes broke Mark's use case and
let us know what you discover please?

Thanks,

- Andrew

I have a vxWorks IOC startup script that mostly uses the VxWorks shell,
but switches to the iocsh shell for some commands.  In 3.15.5 this works
fine, and I see the following:

However, when I boot the same IOC in 7.0.1 I see this:

 

*****************************************

value = 0 = 0x0

<SIS3820.cmd

# Example vxWorks startup file for SIS3820

 

iocsh

So the iocsh commands are not echoed, I only see the epics> prompt, not
the command that is being executed.  This seems like an undesirable
change in behavior?

 

Thanks,

Mark
