I use Telnet quite regularly (from the TSO command line) to get from one z/OS system to another.
It doesn't matter that the system you are going from is referred to by you as a 'host' - in this case, it's just another telnet client. All colours, PFkeys, ISPF screen displays, scrolling etc all work exactly as they do if you're using a telnet client from Windows or Unix or OS/2 or whatever - you wouldn't know the difference. This is what Transparent Mode does. By default the z/OS telnet client opens in Transparent Mode - allowing all screen control characters and key function codes to pass between the remote server and the local client. Since it recognises 3270 datastreams, I would say that this makes it a TN3270 client. The only key that is not passed through is the ATTN key. This 'breaks' transparent mode and reverts to linemode, enabling you to enter telnet control commands such as 'quit', for example. You can force z/OS telnet client to open in linemode by specifying that as an option on the initial command line. If you try to do that to a 3270 telnet server, you will get an error message (or should do anyway) informing you that transparent mode is required.
