Ah, excellent! Good to know that it is more ubiquitous than I suspected. (The lack of ^T on Linux really annoys me too. What is worse is that it isn't just a matter of the line discipline sending SIGINFO for ^T... because Linux doesn't have SIGINFO at all. Means you can't even really hack up a pty wrapper program that emulates it, unless you are willing to have everything use a different signal in lieu of SIGINFO...)
