Solaris made the distinction between B0, which means pty hangup mode, and any other baud rate: https://docs.oracle.com/cd/E88353_01/html/E37851/pty-4d.html But... why not implement a pty bandwidth limitation layer? You say, I need to justify it? It's for, uh... protecting the system from unrestricted pty usage DOS attacks! Yeah. That's what it's for. Craig Milo Rogers
