If you have a system with a remote console you dial into then with this patch applied a modem drop eg from a bad line will no longer drop any live session and ensure a login is required as it was before. That's a pretty bad regression case. If you are running a serial console and want to leave DTR high either wire the cable that way or don't set HUPCL in the first place. The technology for fixing this problem already exists!
