There is a node where I ssh into and start a script remotely by Robot Framework (SSHLibrary.Start Command or Execute Command). This remote script starts a telnet connection to another node which is hidden from outside. This telnet call seems to be a blocking event to Robot. I use RIDE for test execution and it simply stops working. I can send stop signals inefficiently. Is it possible to spawn telnet within ssh?
We haven't exactly used the method with telnet but with another ssh session or other shells that we cannot access otherwise...
Open an ssh connection to the first machine. 
On this connection, use SSHLibrary keywords like Set Prompt, Write and Read or Read Until Prompt to manually open a telnet connection to the next machine.
Write and Read Keywords can be used a bit like the expect and spawn...
Is there a way to use telnet within an ssh connection in Robot Framework?
