Plink/Putty telnet help

I need to create a batch file for work that will allow the user to connect and send a single command to a device, no login required.

I've decided to use plink/putty to implement this, as it seems to be the simplest way. However, I'm very new to telnet, and I can't figure out out to get plink to send the commands.

for testing, I am simply trying to connect and send commands to gmail. I can do this in putty without any issue by connecting to smtp.gmail.com 25. I have saved this as a session named test1, and can then connect in the command prompt by typing "plink test1", and it connects, but I have no idea how to send any further commands. I cannot even type in the command prompt window at this point.

Any suggestions?

Thanks

Plink is just the connection tool to get you to telnet or SSH to another machine using a CLI. Once you're connected you just need to send the commands over the telnet session then, aka, the command prompt.

This is what I thought as well, but when I connect, I cannot type any further commands. The curser is there but typing has no effect, so I cannot input any commands.

what is the command you are using to connect with plink? There may be some options in there to return to the command line. Otherwise, if you aren't going to be doing it via script, why don't you just use the pre-installed telnet?

Are you using telnet or ssh?

I don't know about plink, but ssh client software on other systems allow you to send a remote command to the server when you connect, something like:
