as a last choice I can use `kill -* $PID` to send the required signals, but this seems like a poor choice.

Are you perhaps looking for kill?

my problem is I can only send the interrupt signal via keyboard keys.

huh? You've proved that this isn't true in the very next sentence.

Maybe I need to rethink my whole approach.

This seems to be your question, but it can't be answered (well) since you didn't tell us what you are trying to achieve.
