Overview:

When establishing a direct telnet connection to a Biamp Tesira it may require a handshake to open the Telnet session. The following is a Muse Automator example flow that handles the handshake requests and gets the connection established. 

Example Code:

This is only required if you are using a direct Telnet connection and not using a Biamp module.
