How to write a simple ttl script macro
Tera Term is an open source terminal which is similar to putty. It supports a Script Language called "Tera Term Language" or "macro" which can be used to automate the CLI based user action. Using this script we can do a lot of automation. The beauty of this script are that these script will be running in host computer and commands are executed on the target.Which means even the target goes for reboot the scipt will be still running and even we can capture/ automate certain tasks which involves reboot.Also no matter whatever the target we can develop script as these scripts are running in the hosts (windows).
