Looking at the code, I'm going to guess that it's largely historical. I'd guess that original core code was originally written for MS-DOS (main.c? RLY?), and once they got it working, they never went back to fix things. Even if it wasn't the most efficient way to do things, I suspect most of the blind community didn't care once it was working --- and they probably didn't have anyone who really understood the tty line discpline layer, since it wasn't very well documented. - Ted
