I have a DOS app (imagine that 🤣) which communicates over a serial RS232 port. I'm using Hal's mega-build to capture some serial logs, however, it would be very advantageous to monitor the activity in real-time as the app is used.

I was going to try and tail the log file but quickly realized it's buffered and not actually written until Dosbox is closed. What would be the best course for me to be able view serial traffic in real-time?
