SecureCRT, Cisco – Echo Flow Control Paste

To help prevent overwhelming Cisco devices while pasting in large configuration files, user miked provided a script that you can use in SecureCRT on the Van Dyke forums.

Demonstrates how to send data from the clipboard to a remote system, sending each line one at a time and waiting for prior lines to be echoed back by the remote system before moving on with sending subsequent lines. This is one approach to prevent overwhelming remote hosts like cisco devices that don’t implement any SSH flow control and therefore are incapable of accepting data as fast as SecureCRT normally sends it.
