Raspberry Pi - Send command via USB/Serial connection

We have a board that is nearly identical to a Raspberry Pi. It is running Debian with some custom voice recognition software.

We have a client that wants us to send commands via a Serial connection. However, for a variety of reasons we are going to have to use a USB to Serial converter coming out of our board right now. Like this one...

https://www.amazon.com/adapter-Benfei-Prolific-Chipset-Windows/dp/B0753HBT12/ref=asc_df_B0753HBT12/?tag=hyprod-20&linkCode=df0&hvadid=242045434535&hvpos=1o1&hvnetw=g&hvrand=15059267281247624401&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9026833&hvtargid=pla-397003917010&psc=1

So the task at hand is to write some simple code that grabs text and sends it out via USB.

Currently, our voice commands can be interpreted locally in two ways. One is via a log file that the system creates as voice commands are recognized. Another is via a local websocket. Every recognized voice command is sent there and there is a local web interface that interprets the commands currently. Below is a rough version of the code logic depending upon which method is easiest.

- Listen to websocket

- When new command is recognized, copy the text

- Send text out via USB

OR

- Watch log file

- As new entry is created, copy the text (and remove some of the extra characters from it)

- Send text out via USB

This solution is the final step in us landing a HUGE contract. This will easily develop into full-time work for multiple developers in the next few months if we do it right.
