Currently I have tera term directly setup to receive serial data sent from a charging/discharging battery through a COM port. Is there a way to then send this data after it enters the tera term terminal to an Arduino via USB using TTL Macros? The reason I am trying to accomplish this is to use the Arduino to find specific parameters within the data which can automate a progress light.

I have really not found any useful forums or blog websites that help me find a solution to be able to transfer the live data.
