Looking at the code yes this would be per line - but I vaguely remember seeing it for every char - this was when debugging a systemC model for 8250. Its been a while... I'd added prints in the model whenever IER would wiggle and it was just being written with 0's again and again when in the early polling based printing mode. I'll send a revised version with fixed changelog.
