a.) I don’t primarily use a linux system
b.) The train isn’t connected to a computer because I’d rather not leave a computer running outside my front door.
c.) That doesn’t seem any simpler than my current implementation.

But thanks for the suggestion.

something like

cat /dev/dsp0 >~/desktop/forward

then hit crtl c after you were done

then use a hex editor to grab only non null blocks

then after you have these files for each input

created a bash script like

#!/bin/bash

forward(){
cat ~/Desktop/forward > /dev/dsp
}
back(){
cat ~/Desktop/back> /dev/dsp
}
whistle(){
cat ~/Desktop/whistle> /dev/dsp
}

stop(){
cat ~/Desktop/stop> /dev/dsp
}

main(){
read command

$command

main
}

so you can just type forward, or simplify it to a number

just send it back out
