I am working on an IOC for a device that has its control interface through telnet. The problem is there is a welcome message that appears once every time I connect to the device using any telnet interface. The welcome message is in this form:

 

Hello world command shell

Type ‘?’ for help

> 

 

And then I have to send “scpi>” in order to start the SCPI mode. Is it possible to ignore this one-time message and send “scpi>” just once in StreamDevice?

Have you tried a global @init handler? 

The documentation [1] seems to suggest that this could work.
