Hi Nolan,
What version of SecureCRT are you using?
Changes in SecureCRT 8.0 (Beta 1) -- January 28, 2016 (8.0.0.1011)
-----------------------------------------------------
New features:- Added a "Send Characters Immediately" mode to the Command window, which makes it possible to do the following in one or multiple sessions: stop commands using CTRL+C, edit files using an editor such as vi, send escape sequences, and do tab completion.
If v8.0 or later, if you enable
Send Characters Immediately, issuing a
Ctrl+C should interrupt the output. (It did in my tests to Linux remotes.)
